Social account could not be connected. Please try again

I am facing the same problem. I tried using Chrome, where I had to login to apple ID via Apple's website (Unlike on Safari where the Apple ID popup shows up as a window and I just use Touch ID to use it) and still didn't work. In the URL after am redirected to Adobe's website after loging in to Apple ID I get this at the end of the URL "connected-accounts?error=invalid_person".

Do you mean on, with, this forum system?

And I must ask, "Why" would you want to do that (connect your whatever "Social" Account to anything Adobe)?
