I have the same problem as Siestauser above. Within Creative Cloud, I'm using Lightroom Classic Desktop, but any amendments or additions to images in my Collections folders there are no longer being synched to my Cloud operations, i.e. Lightroom Cloud or Lightroom Mobile.
Can anyone at Adobe help please.
Incidentally, noted from other Threads that this was a big issue back in 2014/2015. But correspondence now closed on that thread by Adobe.
