Since the last update on all my family’s devices the loading of the app with the auto-signon to Microsoft account takes 5+ minutes to finally get logged into the system to play.
We have multiple versions of Android, several Pixels and even an older LG V35, plus a Lenovo Chromebook. All suffer this bug currently.
We’ve already gone through the usual attempts to fix or work around this, cache clearing and re-installs, etc… the issue still persists.
