I have synced all my photos from Lightroom classic to Lr mobile and sometimes import photos into LR mobile and move them in LR classic after sync. So source is LR classic and all LR mobile imported files are deleted in the cloud after sync to classic.
But now is see that the photo number in LR mobile / cloud is 40 photos higher than in classic .
is there any way to identify which photos are in cloud only and not in classic ?
Presumably you are comparing the All Photos total in LrM with the All Synced Photographs total in LrClassic, is that right?
One possible explanation for the difference would be videos....any videos you add in LrM are included in the All Photos total, but are NOT included in the All Synced Photographs total in LrC (even though they do download into Classic from the cloud, they are then flagged as unsynced, so don't get added to All Synced Photographs).
