Online Soccer Manager Does Not Allow Changing Manager Name on iPhone Login

When I first logged into Online Soccer Manager with my iPhone account, the game automatically created a manager name for me. Since this name cannot be changed, I tried deleting it to start fresh with a new manager name. However, now I keep receiving an error message and cannot proceed with creating or logging in under a new name.

This situation is very frustrating because the manager name is an important part of the game identity, and players should have control over it. Being locked into an automatically generated name takes away personalization and enjoyment.

I request that OSM resolve this issue so I can log in with a new manager name of my choice. Players should be able to update their manager names freely, especially when first signing in with external accounts like iPhone.
