I created a synced collection on my Mac with LR CC Classic and erroneously put all of my photos inside. LR started to sync 70000 photos. When I noticed it, I deleted the collection but LR is still show a sync counter of almost 68000 photos.
Any idea on what is going on and on how to resolve this situation?
Go to the LR preferences then to the Lightroom Sync tab and select the Delete All Synced Data button.
