I recently encountered the issue of my account being blocked due to too many concurrent sessions being used and I found out this was a result of my account suddenly being associated with someoone else's account, surprisingly (or not) one of my customers.
TV support sent me to talk to the admin of that account and I was able to release my account from them, but now I found out that my personal email (not the one registerred with the account) cannot be associated with it, and now they are telling there's another old customer of mine that my email is registrred with.
Needless to mention that even if ever logged on to my account on their systems, I never actually registerred myself with them, and so it's something that happened in the Team Viewer's infrastructure changes (I didn't even know what's a "Company Profile until lately...), but I keep getting tasked by support to contact all kinds of masked email to try and release my email from their hold.
I was even told by the support person that "it's my fault" my account got to that state because I didn't open a company profile...
If anyone knows how to get out of this not-so-magical loop, he'll get my endless appreciation...
