I have implemented Firebase Phone Authentication in my FlutterFlow app, but OTPs are not being sent to numbers.
I have implemented everything given in docs and on youtube guide
Test numbers added in Firebase doesnot receive OTP.
I have enabled Phone Authentication in Firebase and entered the correct SHA-1 and SHA-256 keys.
I am on the Blaze Plan, so there should be no quota issues.
Why is OTP not being sent, even to test numbers?Is ReCAPTCHA mandatory for real OTP delivery?
If I want to publish my app and allow real users to log in with their phone numbers, what steps should I follow?
