I have developed an AppEngine application that I am transferring to a different company, and I would like to remove my own personal access from this application after the transfer to the other company is complete.
The first step that I took in transferring the ownership was to invite the other person as an administrator with an "Owner" Role.
However, after the transfer, beside my name in the Admin/Permissions console, I see the message "The only SMS verified owner cannot be removed" - which appears to make it impossible to remove myself as an owner from the application.
It seems that the other "owner" cannot verify their account via SMS, since they already have administrator access to the application.
How can the other account get "SMS verified" so that we can then remove my account as an administrator from the AppEngine application?
