P: Lightroom Classic: no longer syncs completely, successfully.

Hi Rikk -

Thanks again for the quick response, and thank engineering too for sifting through the sync logs so fast. Sadly, the "Rebuild sync.lrdata" did not help. Tried three separate times, even after log outs and reboots.

HOWEVER, I can say that @4888644_koopman 's discovery that any photos with "Unknown Lens" as a metadata field will fail an entire sync! I just removed 256 such photos from two dozen different collections, and then synced the remaining 1,000+ photos with absolutely no problems whatsoever. For me (and Jens apparently) THIS is the exact bug.

Funniest thing? ALL these photos used to be in sync with no problem. Also funny: many of the photos are from known cameras, sometimes with built-in lenses. The iPhone 4s after all is a pretty known value.

Hope that helps engineering squash the bug. Now can I have the last 100 days of my life back and my CC subscription refunded?

Hi, Rikk,

I fully understand that you need to focus on the issue case by case. I will start a new thread and keep following your progress here.

Thanks.

@Huaqing Yin 

I do not think this catalog renaming is in-play for a sync issue.  

Sync issues tend to be very specific to a user's state and conditions and, in general, and unlike other threads here at feedback.photoshop.com they are best served as a single poster per thread.  When multiple users post in a continuous thread, it tends to cause some confusion as to who is saying what about what.  That is why this thread is focused on Hans and his specific issue. It is very hit or miss whether the solution for Hans will apply to other customers.  

We want to help everyone with sync issues but it is very difficult to do fragmented across a multi-user thread.  Often, persons not fluent in the forum come in to assist and have to parse the original posters issues separate from other subsequent posts. 

What can you do to help us help you? 

For Sync Issues Only: 

Start a new thread that contains as much information about your:

• System
• Current State
• What's been tried before
• And any other information you feel is pertinent

If we can keep sync-related threads cleaner it helps us move through them more quickly.  I would recommend you and @jens_koopmann both consider doing this.  Feel free to copy and paste the information you've shared here already into your new thread-unless that information is out of date. 

That said, working through a forum introduces a time delay based upon our various time zones, schedules and work loads. (at time they do give me a day off here and there so it may take a few days for a round trip response). If faster service is necessary, I recommend contacting Adobe Customer Care for Phone/Chat support. 

If you prefer to work through the forums, I welcome you to create a new post as outlined above.

Thank you for your patience and your support of the Lightroom Classic product.

From Engineering:
According to your log file:

"There are 172 documents missing from docStore and 632 pending lrcat changes are yet to be processed.

Since the no of images synced is very less .. a quick “Rebuild sync.lrdata” would help here."  

This would be going to Preferences>Lightroom Sync and holding down the [Alt/option] Key and then clicking on the [Rebuild sync.lrdata] option.  Even if you have done this before. We would like to do it again and see if sync moves. 

Hi, Rikk,

I have learnt from another forum that changing catalog file could cause sync issue. When I upgraded my LR CC to v10, the system changed my catalog file to orginal_name-v10.lrcat. Could this be the root cause of my issue?

do you want to work on case at same time when you are helping @hans_rupert? or should I get another Adobe expert to help me? please advice.

Thanks.

Yin

Got it. Please leave your link up for a week or so. As soon as I hear back from the team, I will update you. 

Thanks Rikk; just sent you a link

Thank you very much, Rikk. I just sent you the link.

@hans_rupert 

I've emailed instructions for the log file. I will respond on this thread once Engineering has reviewed and replied.

Jens -

Furthermore, all I'm trying to do is get back to the 5,000 photos I had successfully synced over a few years. The last time they were all synced just fine was in July! I'm not even trying to add any new photos, I just want my LR sync to work again.
