Xamarin.Forms and App Center: unable to install iOS release on iPhone 5s

Question

I'm working on a Xamarin.Forms app that I would like to deploy for some testers through App Center.

In Visual Studio, I'm able to build and deploy the app on a iPhone 5s simulator, even if the iOS version is 11.4.

In the info.plist the Minimum system version is set to 8.0. In the iOS Build settings, the SDK Version is set to default. On my machine, the current version of XCode is 12.1.

On App Center, I've managed the Build Configuration like this:

• Configuration: Release
• SDK version: Xamarin.iOS.14.4
• Xcode version: 12.2
• Build scripts: None
• Build type: Device build

When the build is finished, I'm able to install the release on iPhone XS (iOS 14.2) or iPhone 6 (iOS 12.4.8), but not on the iPhone 5s (iOS 12.4.9).

I get this the error message "The developers are working on a version for your device".

However, I've added the App Center profile on each devices, and the iPhone 5s appears in my registered devices.

On App Center, I've tried to use older configuration for the Build Configuration:

• SDK version: Xamarin.iOS.14.2
• Xcode version: 12.1

But the result is the same. Is this normal?

From the docs

If we detect that the device that the tester is using isn't on the list of provisioned devices for the .ipa they want to download, then we show the message "The developers are working on a version for your device."
