Thank you so much for your response and clarifying matters One more question if you don't mind I am able to create a BLE device that advertises itself as a Bluetooth SIG Service UUID such as: 180D - Heart Rate However, a different type would make much more sense for the product: 1826 - Fitness Machine Using that Service UUID does not show up under WatchOS > System Settings > Bluetooth Is there a reason only some Bluetooth SIGs Service UUIDs are allowed and some are not? A couple of WWDC videos say if this type of System Settings BLE connection is made on the Apple Watch, versus at the App level, the connection is more reliable, is able to connect in the background, and gets data sent more frequently. If our product though makes more sense under an Bluetooth SIG like 0x1826 how can I make that type of connection? Note: I'll make sure the guidelines are followed. Thanks for the link

Hello. No I gave up. Not sure if Apple Media Services is actually supported or has just been forgotten

Unfortunately, same issue. I can't even wear my Apple Watch anymore. Had to turn it off and put it away to get any work done.
