I have to manually check each file I've created in the previous version and move them to the new Express one by one? Seriously, Adobe?
That option is so that if you still want edit access to projects created on mobile you cna keep the files there. Any files moved to the new Adobe Express won't then be editable in the mobile app until it, too, is upgraded to the new version.
I use desktop exclusively and the files I previously created are not found in the new Express. It gives me the option to bring them over only by checking each one and saying, "move file". I have dozens that I continually use and modify. This is freaking insulting for the amount of $ we pay for CC (I use multiple applications and have been paying for over 5 years).
Oh, and I can't use Firefox anymore, either. I. am. so. mad.
Adobe, please escalate this issue immediately.
