Too many Requests. Try again later on first try in partner account

Whenever i try to transfer a store from Partner account to client email, add a team member or even login to my collab stores, it shows a security challenge of sending sms to my mobile number.

But it never sends a code and on very first try it says too many request try again later.

Support sends template replies and asks to verify again my identity. and then they sleep.

whats the issue and solution for it??
