Play Integrity Token fetch failed, falling back to Recaptcha-9: Integrity API error (-9): Binding to the service in the Play Store has failed. This can be due to having an old Play Store version installed on the device.

Hi everyone,

I am trying to activate phone otp verification through firebase in my flutter app. And after adding all the necessary code for the verification, when the button is clicked, I am getting this error:

ForceRecaptchaFlow from phoneAuthOptions = false, ForceRecaptchaFlow from firebaseSettings = false

Has anybody ever faced this issue? Can someone help?

Also I have a debug.keystore file in my android/app folder already and have also added the SHA-1 and SHA-256 to firebase.

Did you get the app from Google Play? Do you have the play signed SHA keys in the Firebase console?
