Intermittent AVD Host Pool Login issues with WhfB endpoint, SSO, Entra ID Auth & MFA via Cond. Acc.

tommykneetz - hey thanks for getting back to me, and yes (I missed an important part of the config out) - I do run FSLogix user profiles from an Azure Files Share.

Stuck FSLogix processes from a previous login are an interesting possibility, but I have tried rebooting the host and then trying to login and get the same behaviour, so I don't think it can be that in this case.

I have also tried rebooting the end-point (turn it off and turn it on again). Made sure the Remote Desktop app is fully updated, reset settings etc.

I have tried switching between when the end-point is both on our corporate network (no MFA needed) and on public WiFi (MFA needed).

The same user can connect to another Host Pool they have access to - just not the one in question (and they are configured with the same settings for the host pool and MFA etc).

It just seems to be time - you give it a few hours and it works again... But I can't really live with this for my users.
