I just updated my iPad Pro 2020 to iPadOS 14.3. I'm also an Apple One Premier member.
When I try to download the Apple Fitness app to my iPad, the App Store doesn't let me. I get an error message: "This app requires specific features not available on this device."
Apple's announcement states
For usage with iPad, Fitness+ requires iPad Pro, iPad (5th generation or later), iPad mini 4 or later, iPad Air 2, or iPad Air (3rd generation or later), running iOS 14.3.
It looks like there might be a problem for iPad users right now. I can get it to work on my iPhone so I know it's available. Is there a way to download this to an iPad?
