Sync buttons next to collections have disappeared.
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).
