signInWithPhoneNumber - INVALID_APP_CREDENTIAL sometimes

[PierreCapo]

Issue

Sometimes, when using the function signInWithPhoneNumber, Firebase Console reports the error: INVALID_APP_CREDENTIAL and our users can not sign in.

I am not sure yet if they receive the OTP code as I am unable to reproduce it at all on my phones.
This issue happens for around 5-10 users per day. I would say that's around 10% of our users that sign up. Other ones are fine.
We haven't had this issue on Android, but we have very very few users on Android, so that might be just pure luck.

Curious to know if other people face this issue.
Given there is no potential race conditions and this problem happens for a small subset of users on different iPhones and iOS versions, I suspect some "infrastructure" related issue.

Thanks for your work the invertase team 🙏

[srimalfernando]

I am having the same issue.
My project also running on version 21.0.0

[craigthornton]

We are having this issue using Xamarin libraries. It only happens to a very small number of iOS users on newer iPhones

[youssdevx]

We also have this issue. We discussed this with Google support team and they told us that it could be related to "jailbroken devices"... Obviously, I don't think that this is the problem here.
I'm still waiting for Google to provide us with a real explanation

You need to check if you implemented App Attest correctly => https://rnfirebase.io/app-check/usage
