P: I would like to synchronize over LAN/Cable instead of internet

Carlos, it sounds sounds great in theory. I wonder if you have any secrets how you are able to do that. It is April now and I am still waiting for my photo shoots from August of last year to fully sync to my Lightroom Mobile tablet. Adobe tech support explained it will not happen in the background, but that I need to keep Lightroom Mobile and my screen on. Basically babysit over 30,000 photos. There needs to be better option if Adobe will not be willing to address this major problem... Over a cable or wifi would be a good start until they fix this...

Well, I finally gave up. It doesn't appear that the combination of Adobe and Apple are going to give us what we want. Apple has opened up the iPad, but even with all of the new features of iPadOS, nothing can fix the Lightroom problem for traveling photographers. At this point, the only solution would appear to be Lightroom Classic for iPad; we're gradually getting Photoshop, Illustrator is on the way - if we yell loud enough, maybe they'd add Lightroom Classic in a few years?

In the meantime, I did some research and decided to give a Surface Go (8GB/128GB) a try. It's nowhere near as fast as any recent iPad, but it does fit in the same space as an 11" iPad Pro, can charge over USB-C, has a decent trackpad on the Type Cover, and it runs a full version of Windows (after you make the free switch from Windows S), so it can run Lightroom Classic.

It takes a while to start LR up, and it's no speed demon once you're in, but for my 20MP Sony and Olympus images, it's actually pretty usable for my purposes. I can import, keyword, and do some adjustments (a bit faster if I let it generate smart previews), and when I get home, I can just export the catalog and import it on my desktop Mac. I did add a 256GB micro-SD card to make things a bit easier, and I can back up to a small USB-C SSD on the road.

Not sure if I would buy the Surface Go at full price ($679 for my setup with an included Type Cover), but I got it on sale for $499, and also was able to save $20 on a year of the Photography Plan with the system purchase, so that brought the full cost down a bit more. I'll bring an iPad mini when I travel instead of the 11" Pro (for reading and web browsing), so the overall weight of my kit won't go up dramatically, and I'll finally be rid of the headache that Adobe is so reluctant to fix.

Feature request; please add syncing raw files from LR CC to LR CLASSIC with a USB-C cable on the iPAD instead of via the Cloud. And the ability to only use syncing via the Cloud for the Collections via Smart Previews. Uploading and downloading 80 GB raw photo files through the Cloud when using my iPad during travel is too slow, it takes forever to upload and when I come home forever to download. The whole process slows down my workflow instead of improving it.


Cons of cloud transfer:  

• It eats up too much wifi bandwidth and battery from my iPAD on my travels
• back at home I do not want to wait untill everything is up in the cloud from my iPad to than download from the Cloud again on my Desktop.
• I do not see clearly what has been uploaded and what not, plus the raw files are somewhere hidden on my iPAD
• files imported in LR CC (raw) are different than the ones downloaded from LR CLASSIC folders to collections (smart previews only). It's confusing when you want to delete files, there is a risk of deleting originals.
• Creative Cloud storage requires the same amount of storage on your hard disc, so it is not truly cloud storage (like online-only on Dropbox)

Instead of importing and working on the RAW files in LR CC, we should be able to work on the Smart Previews instead. So the workflow is the same as if the images are coming from Collections in LR Classic. The raw files should be imported on the iPAD where they are visible on the iPAD folders and easy to copy over to an external drive or computer.

Without wifi, it is not possible to transfer images, captured by the Lightroom camera and imported directly to Lightroom on the iPhone, to another iOS device (iPad) by direct connection. Images from the camera roll can be imported but images already in Lightroom cannot. This is a problem when using the Lightroom camera (on the iPhone) in the field, with no wifi, and needing to edit those images on the iPad. All devices are running iOS 13.3. The only alternative is to use another camera such as Halide which imports to the camera roll.

I'm sure it's no reflection on your IT experience but...you are conflating two entirely different issues.   Whilst maintaining multiple versions of a singe dataset is fraught with technical difficulties... this concept has absolutely NOTHING to do with the reason why a local syncing option is unavailable on LRM. The decision to leave LAN syncing out of mobile is an ADOBE business stratagem NOT a technical issue AT ALL. (I worked as a OS developer for many years)  I made a post about this over three years ago on this very thread.
Whilst the cloud may work well for you there are many many scenarios where it is sub optimal or downright useless.

With this new update, the ability to synchronize the folder (album) on demand would be perfect to 😉

I just exported some raw files in Lightroom Mobile as dng files and then airdropped them to my Mac in tact! I really appreciate that Adobe would make Lightroom more usable to a wider range of folks. Thank-you. It would be awesome as well to have full keywording function & transfer. 

Oh my god ! New update of LR Ipad ! It is now possible to import directly in Lightroom, and export DNG !!! Oooooo ! Wonderfull !!! I tested with 200 CRAW files and word fine ! Good job Adobe ! Very good job !  Thanks for this update !!!

Yes an export with settings would help too. But that would also need the limit of 15 files to export at once to be removed. That would be the offline solution.

And for slow/bad connections the "only upload smartpreviews to the cloud " option.

I actually like being out where there is no cell or internet service.  Very refreshing.
