I'm unable to load provisioning profiles on Visual Studio 2019. It just gives a default list. I have the latest Visual Studio 2019 and latest XCode on my Mac (Mojave). After 2 days of pulling everything apart I found this in the Xamarin Logs (AppData\Xamarin\Logs\16.0). It'd be all-time if these errors were flagged somewhere in the visual studio IDE. Yes my bundle ID matches and i'm signed into the right account and my certificates aren't expired etc etc.
An error occurred on client IDB1610545 while executing a reply for topic xvs/idb/220.127.116.115/get-provisioning-profiles ---> System.PlatformNotSupportedException: Operation is not supported on this platform.
