It appears that the issue you are experiencing with the Windows App version 11.0.0.64, where all AVD connections are failing and stuck on "Securing connection to gateway...", may be related to the recent update. Since you mentioned that the same device models work fine on previous versions, it is possible that the update introduced a bug or compatibility issue affecting the connection to Azure Virtual Desktop (AVD).
Here are a few troubleshooting steps you can try:
- Check for Updates: Ensure that there are no subsequent updates available for the Windows App that might address this issue.
- Reinstall the App: Sometimes, reinstalling the app can resolve issues caused by corrupted files during the update process.
- Network Configuration: Verify that the network settings and firewall configurations are not blocking the connection to the AVD gateway.
- Contact Support: If the issue persists, consider reaching out to Microsoft support for assistance, as they may have more insights into issues related to the specific version of the app.
Since this is a known issue following an update, monitoring the release notes for any fixes or patches from Microsoft would also be advisable.
