stuck on "configuring remote pc" after first connection

We are sorry you are running into issues. To discuss issues we recommend to share your problem on our Tech Community forum (https://aka.ms/wvdtc) or open a support ticket after you have reviewed the troubleshooting options in our documentation (Windows Virtual Desktop troubleshooting overview - Azure | Microsoft Docs)

It appears to be a problem with the app. If you are trying to connect to an older PC, before it connects it has a screen that says "Identity of remote PC can't be verified." If you check the box "Never ask again for connections to this PC" and then connect, you will never be able to connect again (for my XP computer, Windows 10 computer still connected). Apparently, it prevents asking and answering the question when it should automatically answer "Connect." The only solution I found on my Android was to delete all the App data (App Info, Storage, Clear Data). You lose all your connection data (PC's, Gateways, and User Accounts) so you're starting all over.

Me too

same as jfrandol said

not my Windows 11 in my local network.

but windows 10 local and remote instance

I have the same issue,  though an alternative rdp app on the play store "aRDP" still works fine.

And the Microsoft App can connect to some of my remote desktops, but not my Windows 11 in my local network.
