Betreff: Sign out of devices below to continue...

7 years later, I have the exact same issue but with 8 copies of the same device. The solution to this problem, signing out to all devices doesn't clear up the issue that I should be able to sign in up to two devices while working on one at a time. It will continue forcing me to sign out of one of them when i turn on the other, because it acts like that one device is more than one.
