Can't remove work iPhone from iCloud & MDM bricked my new iPhone
I recently left a company, and I need to return my work iPhone that they provided.
Unfortunately this work iphone is tied to my personal icloud account - the phone number and device can MFA into my personal icloud. I have logged into icloud on a web browser, but it doesn't let me remove it because of "Stolen device protection" and it says I must remove it from an apple device.
So, I recently bought a new iPhone and entered my iCloud to then remove the aforementioned work iPhone, and now my new phone (that has nothing to do with the company) is now bricked with my company's MDM.
My former employer's IT department says that they have removed the work iPhone from their MDM, and they say that there's nothing they can do about my personal iPhone and that it is not anywhere on their MDM.
What can I do to release my personal phone from their MDM and also kick the company phone off of my iCloud account?
Thank you!
