File Sync Links that may help... all the links I have, since I don't know the cause of your specific problem
-sync and email link https://community.adobe.com/t5/Get-Started/Email-link-of-file-in-personal-CC-folder/td-p/5944719

I imagine the root of the problem is the fact that clicking the cloud icon in the toolbar shows an unmoving progress bar stuck on "Getting storage information," but I have no idea why that's happening or how to fix it.
And just like that, with zero further action on my part, it starts working again. Gotta love this bug-ridden product. Always a pleasure.
Wait, so how exactly did you get it to work?
Mine says the same thing and its stuck on updating at 23%.
I didn't do anything; it just randomly started working again on its own. Must've been a temporary glitch on Adobe's side.
