we will have bigger problem. Why removed?
Also, when account is added automatically, and if we make any changes in profile within App, it get lost on re-login to App
This has been removed a long time ago. What options are you changing and you cannot re-login? Can you be more specific so I can find a solution of your problem
You have to disable re-provision on startup from Management Console and then change the name. Click on the extension > Phone Provisioning > Disable Re-Provision on startup.
