version 17.6 is busted for iOS
Once this version was released, there is a constant loop of being asked to login to service provider (Sky) and when re-directing, it opens the main watchESPN page in the pop-out box, and then complains that you have to watch the content on the app. However, it is not possible to watch it on the app because of this constant loop. The error shows up as “watch.provider.raptor.callout” (which was never present before this version) and “watch.provider.troubleSigningIn”.
