In Firebase Authentication version 33.10.0, it is not working in my project when using compile SDK version 35. However, when I use Firebase BOM version 28.2.1, the authentication section works correctly—OTP is generated and received on my phone number.But when I update to the latest Firebase version 33.10.0 while still using compile SDK 35, the authentication does not work. The OTP is not received, and the callback section is not triggered.
Plugins Used: com.android.application Declares this module as an Android application module. Required for building Android apps. org.jetbrains.kotlin.android Enables support for Kotlin in Android development. kotlin-kapt Kotlin Annotation Processing Tool. Required for libraries that use annotation processing, such as Room or Dagger. com.google.protobuf (version '0.9.0') Enables support for Protocol Buffers (protobuf), a method of serializing structured data. Useful in apps that use .proto files, often with gRPC. com.google.gms.google-services Integrates Google services like Firebase. It processes the google-services.json file to configure Firebase services such as authentication, analytics, and database.**

this code use for Call back sending phoneauthProvoder code: Triggered when Firebase successfully sends an OTP to the user. p0 = the verification ID (used to verify the code later). p1 = token that can be used to resend the code if needed. What it does: Saves the verification ID to a variable (verificationCode). Logs the event. Updates the UI (hideMaskingView) and starts a countdown timer for the OTP (startOTPCountdown()).
private val mCallBack: PhoneAuthProvider.OnVerificationStateChangedCallbacks =
