Sync buttons next to collections have disappeared.

[smartprague]

Hi.  I thought I had got on top of syncing bewteen Lightroom classic and Mobile.  I set up some collections in Classic of Photos I wanted to review on my ipad.  They synced fine.  I reviewed them on my ipad and made some changes (I marked them and rated them).  The sync from Ipad to Creative cloud has happened, however when I go into Lightroom classic, none of my collections are showing as syncing (The little button has disappeared).

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the LRC forum so that proper help can be offered.

Check that syncing is not paused in the cloud icon in the upper right corner above the grid.

Thanks Johan.  I did, it wasnt paused.  I found that it was being caused by an error on Sync.  Apparently I had two photos with the same filename.  No idea how that arose, but fortunately I didnt need either, so just deleted.  Switched sync to pause then restarted and everything went back to how it should have been.
