I have an Apple Watch Series 5 and when I start pairing it with my iPhone X it says that it will download the "Activity App" to my iPhone but it doesn't!! When I search the app in App Store it doesn't show the app at all but when I search it in Safari, it finds the app but it says "This app requires specific features not available on this device." I have unpaired and paired my watch and phone again but the same story. I have tried turning my phone and watch off and back on as well as Hard Reset but it didn't help! Can someone please explain how can I download the Activity app???
