Known issues with Android System WebView 139.0.7258.160?

Question

Hi everyone

we have some reports about OAuth2 Login issues on Android devices with Microsoft Conditional Access rules. Some device (very small amount) are not able to login to some specific apps where the OAuth Login is being made with an embedded Browser session.

During investigation we found out, that all users are on Android System WebView version 139.0.7258.160.

Users without issues are running 139.0.7258.158.

We don't know whether this is the issue but I wanted you asked whether other admins here are having similar issues in the last couple of weeks.

Are there any known issues about certificate based logins with Android System WebView currently?

Thank you!

Kind Regards

Daniel

Hi @weberda/Daniel 👋

I’ve checked with the team and there doesn’t seem to be any WebView issue or bug at present.

The best thing you could do is to raise this with your EMM; you need to ensure there aren’t conflicting policies or something else in place that could be affecting WebView (particularly since this only impacts a portion of devices).

The team also recommended reporting this to your OAuth provider so they can look at the logs and identify where there’s a failure that prevents authentication.

I hope this is helpful - please let us know how you’re getting on!

Chat soon,

Emilie
