Please do not discontinue the cloud sync service.
I and many people I know use the Creative Cloud system for syncing files through various devices, not just Adobe sync files, but many other files related to projects. It seems totally ridiculous and a massive loss of revenue to force users into finding another cloud drive service to fill this need of so many users. There isn't even an explanation except "modernizing"., whatever that means.
Yes, I get that some files work as Cloud Sync files, but not with all apps, and I don't like that feature anyway, as I want more control over the files which that feature doesn't provide.
The sync system works great and is such an awesome perk of being an Adobe user.
