I'm developing an app that has the feature to get an OTP, and I've used firebase OTP feature (Authenticate with Firebase on Android using a Phone Number) but unfortunately some-time I'm facing issue like I'm not getting otp from firebase also its not giving any errors at same time. I don't know what was the mistake i did.Need help to solve this issue also I've tried some samples its working properly but when i try to integrate in my project firebase is not sending otp.I want post mobile number to firestore with users current country code for ex(+91,+888).
This what I've tried in my project so far:
