I have no idea why it is happening. My app works fine with debug apk and signed apk. I have added the SHA1 key to firebase console also. But when i uploaded my app and installed it from Play Store then it is not sending the OTP to my phone number. Please help!
Thanks in advance
Did you just enrolled for Google Play App Signing? In that case your key has changed. You can get SHA1 of the key used to sign your apk from Play Store Console.
