Been looking for community threads on APPLE SUPPORT to clear this issue - but EVERY ONE follows the same story: 1. Delete all Sky apps; 2. Reinstall. BUT IT DOES NOT WORK. The threads are then being closed down as "Completed" by "Apple Employees". This option "iphone=>iMac screen" appears helpful, but the Screen Mirroring option on Control Centre gives the following message on iMac: "SORRY! Playback is not allowed on external displays." So I can only think Apple don't want people watching Sky on iMac anymore. I haven't looked at watching Sky through Apple TV - but that would require yet another paid subscription!!
