Sync issues between desktop Lightroom and Lightroom Mobile

[krystiand84061695]

I am running Lr on Mac OS on my desktop and a Lr Mobile on iPad, all updated to latest versions. I keep getting persistent sync error, where around 10% of files will not sync back to desktop LR. For example I will sync a catalog of 5000 images to LrM, make selection (using flags) of about 1500 images, but only about 1300 will appear as selected in the desktop version...Its never exactly 10% but its around that every time. I checked Lihtroom>Preferences>Lightroom mobile and there is no sync activity pending... unselecting and re-selecting wont work either

The files that do not sync back appear to be random, but looks like there are series of 10-20 consecutive images. The problem does not exist the other way round, ie. all changes/selections made in desktop version will sync with LrM with no issues. The cloud collection also seems to be synced correctly... Did anyone else experience similar issues? Is there any way to force desktop Lr re-sync with cloud?

Hi Krystiand,

As you are facing a sync issue with your collection of Images, could you please try creating a new test catalog and import a few images into it and try to sync them to Lightroom mobile and share the results with us?

Hi Krystiand, this sounds like a meta-data sync hiccup.

what you can do to force the sync of the meta-data is when you remove (or just renam) the sync.lrdata file and restart Lr Desktop. This would restart/refresh the sync (metadata only).

Removing the Sync.lrdata might fix whatever the issue is.

You can find the  sync.lrdata file here:

On Mac it's at /Users/<user>/Library/Caches/Adobe/Lightroom/Sync Data/Sync.lrdata

On Win it would be at C:\Users\<user>\AppData\Local\Adobe\Lightroom\Caches\Sync Data\Sync.lrdata

In case you still see the issue could you please send me a LR Desktop diagnostic log  - best as a private message with a downloadable dropbox link.

You can trigger the log via LR Desktop preferences -> Lightroom Mobile and when you hold down the alt key you will notice a generate diagnostic log button

btw. do you access you catalog from more then 1 deskop machine?

Hope this helps

Hi Guido,

Thanks for the reply. Your solution did fix the issue temporarily. I only use one desktop machine, and now even deleting the sync file does not work. The photos still sync up to cloud from the mobile device, but LR Classic cannot see some of the changes even after forced re-sync. The changes made to the files in LR Classic (or CC 2015 for that matter) will not sync up to cloud at all, and around 15-20% of files will randomly not sync from the cloud to LR Classic. Recent issue - out of 1983 photos flagged 'picked ' in LR Mobile, only 1698 show up 'picked' in LR Classic, yet all 1983 will show as 'picked' in cloud. Total catalog size is 6810.

Update:) It does sync eventually, but the lag is painfully loong...
