I have one collection with 169 pictures setup to sync. LR stays with Syncing 11 Photos forever.
I tried to: stop LR, delete the sync data, and restart LR. Didn't help
I had this issue some time ago and sit stop sync, delete the collection, recreate the collection and start sync. That worked. For one collection it's ok, but...
linked the diagnostic file ....
Any idea what the problem is? Lightroom 5 worked fine
I've just send you a private message
