Error Message "This site can't ask for permissions. Close any bubbles or overlays from other apps."

Hi bgilchrist!

It seems like the issue is related to overlays in Kiosk Mode blocking location permissions. Since Chrome worked but isn’t an option, and you've already disabled overlays and tried configurations without success, it might be a deeper issue with how Intune or Edge interacts with kiosk settings. One thing to try could be ensuring that the location permission is explicitly allowed in the device configuration profiles in Intune, not just in Edge. You could also try to adjust any settings related to kiosk mode in Intune, such as allowing background apps or tweaking kiosk restrictions that could be interfering with Edge’s ability to prompt for permissions. 

Hope it helps!
