Login with Google - Error 403: disallowed_useragent

[christiaangombert]

I need to login with Google credentials for a website. Sadly I now get Error 403: disallowed_useragent

This will occur because the Android app makes a login request that Google rejects. The most common reason for this rejection is an unauthorized browser agent (the app is using a deprecated browser agent that Google no longer accepts).

I am aware of this issue - Google actively disallows the login to its services with applications which use their own WebView. In the next release, this will be handled accordingly.
