Can't change Apple Id on Device
Community
While travelling abroad, I got my iPhone stolen.
After dealing with the fact (police, etc), went back to where I was staying and dealing with the fact I was not get it back, started to secure my data, and changed all the passwords I could - including the ones from Apple, using my Mac.
One month later, back home, got a new phone.
And then I remember - "there is still the old iPad".
This one still have the old Apple Id Verification, which does not exist anymore. Every time I try to put the old Apple ID, it sends a message (primarily) to the new iPhone, and changes the password of the new email assigned, but keeping the old email (now of a not valid/non-existent account), which I cannot delete anyhow.
I need to erase the old email (which I can't), and put the new one; I can't event reset its password; it doesn't exist anymore.
Any hints on how to get rid of this loop?
Thanks in advance.
