I design app for chatting but registeration not work when i register by phone number and press next don't open otp screen ! can anyone help me?

show your whole blocks because there is no OPEN SCREEN block here to open the OTP screen.

Extra Note: you should add country code in-order to get the Firebase Authentication work.


thanks, but this solution will be google play accepted my app or will be any problems?

if you mention all the app permissions and uses in Play Console, then there will be no issues
