What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

Since we updated to 20.0.4 version our app starts to crash, we don't get the specific scenario to reproduce it but it's related to RecaptchaActivity , and web views missing or not support all browsers won't work in opera, firefox

          Hi @erikjhordan-rey thanks for reporting.
There was an update to allow devices without Google Play services to use Firebase Auth (click here for more details). Now, it looks like one additional requirement for that is to enable the SafetyNet API (click here for more details), otherwise the flow will require solving a reCaptcha. Enabling SafetyNet requires the following:
Enable the Android DeviceCheck API in the GCP Console
Add the app's SHA-256 fingerprint in the Firebase Console
Let me know if that works for you, otherwise please provide sample runnable app so we test it locally. Thanks
Hey @erikjhordan-rey. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.
If you have more information that will help us get to the bottom of this, just add a comment!
          During this weekend I experienced similar stack traces in crashes:

This happened using a firebase BOM of 27.1.0, and the crashes were restricted to a single user with a HUAWEI Y6 2019 with Android 9. Any other device works fine, the closest device I have is a Huawei P Smart Plus 2019 (POT-LX1T) and there the login/authentication works fine, so I can't replicate the crashes.
I see there's a new BOM of 28.0.1 so I'll try that and see if the crashes appear again.
