Because of changes that Apple recently made to the way provisioning works, Xamarin Studio currently is unable to refresh changes or additions to iOS Provisioning profiles directly. As a current work around, you'll need to do the following:
- Quit Xamarin Studio.
- Start Xcode.
- Select Xcode menu > Preferences... > Accounts and click the View Details... button.
- Click the Refresh button and then click the Done button.
- Restart Xamarin Studio.
This issue will be corrected in a future release of Xamarin Studio.
