I originally set up my provisioning profile, and only had one device. However I am wanting to add a new device. I went to the iTunes Developer Account website, and edited the provisioning profile, and added the new device. However, after downloading the new profile and restarting visual studio, I am still unable to test on the new device.
I also recently updated XCode to 10.3, and i notice that when you click Xcode > Preferences, there is no longer a 'view details' button.
