A final note on this from me, and I do hope that Adobe Management read these forums, is that it seemed risible that Customer Services were apparently unaware of this issue. If they were made aware, they could simply have informed us that it was a known problem that their engineers were working to expediently resolve. Instead, I wasted over an hour on a remote session on Friday and a similar amount of time getting repeatedly disconnected from attempts to web chat on Saturday.
Heads up Adobe, your handling of this incident was unacceptable and will not be tolerated by your Cloud user base if you fail to learn from your mistakes!
