I've problem with syncing where it just stuck there (100+ photos to sync). I've tried several solutions like sign-out & sign-in back, deleting Sync.lrdata & re-installing LR. Since I deleted Sync.lrdata, the problem seems to got worse. Now I'm stuck with 2.731 photos to sync. Deleting Sync.lrdata again only result with same problem, stuck on 2.731 photos to sync. Observation on Sync Activity show majority of the photos consist of old and new photos with "Metadata" on Sync Details on all of them. Anybody have experience on this problem before? Any solutions I should try?
Seems like the problem is server side. After a day, the sync seems to continue slowly, then at normal speed after an hour or two. Everything is synced perfectly now.
