I previously had a phone number saved in an auth user. If i try to remove the number I get same number already exists. I am testing a verification process, and now I cannot remove the number to test re-adding it.. v1.5.5
TL;DR
Developers are encountering an error stating 'number already exists' when trying to remove a phone number from an auth user. To resolve this, try making an API call manually to update the phone number and set it to null. This should allow for successful removal of the phone number.
