Here's a little information about your CC Teams vs. Personal CC account.
1. I'm logged into my CC Team account at the studio
2. I go online and log into my personal account to write in Communities.
3. When I tried to write up a comment, Communities sees me for my CCTeams login and not for the Adobe login I used on Chrome.
Just strange. Thought I'd post it, and see if anyone else using CC Teams has experienced the same.
There is no connection between the Creative Cloud license manager and this website - it will not automatically log you in, so if that is happening it can only be caused by cookies stored in your browser (created when you log into the forums or the main adobe.com site). The forums also have no idea if you have more than one AdobeID.
Oddly - it asked me to update my "nickname" using my Teams login. I could not cancel away from it.
It could likely be cookies stored from the main adobe site.
