Disassociate from company managed Apple-ID
My phone was configured from an iCloud backup of another (lost) phone inherited from an employer. The old phone already had been successfully logged out from the old company managed ID, but yet it kept prompting to log in with the old company managed ID. The same goes for the new one which I have bought myself.
How to disassociate the phone from this unsolicited prompting?
