Hi,
I see nothing here regarding MSAL's WithUnoHelpers extension, which does nothing on .NET 6/7 Mobile.
Do I need to enter an issue about it? Thanks.

There's no change to the MSAL library from Uno but you do need to update to the latest MSAL library from Microsoft

I don't understand as even the MSAL samples call WithParentActivityOrWindow. See here: https://github.com/Azure-Samples/ms-identity-dotnetcore-maui/tree/main/MauiAppWithBroker.
Am I missing something here? I had to call WithParentActivityOrWindow on my .NET 7 Android app as I kept getting an InvalidOperationException with WithUnoHelpers. Thanks for your help.

@Medality I'll review uno support for MSAL this week and confirm what's required
