Permissions.CheckStatusAsync<Permissions.Bluetooth> on iOS returns Granted when don't allow is chosen

ckrutsinger commented 6 months ago

Description

status = await Permissions.CheckStatusAsync<Permissions.Bluetooth>(); is returning PermissionStatus.Granted even though I choose Not Allowed.

Steps to Reproduce

iOS ONLY

Include this in Info.plist:

<key>NSBluetoothAlwaysUsageDescription</key>
<string>app collects location data to enable vehicle services including current location and event location</string>

Upon app install, you should be prompted for Bluetooth permission, choose "Don't Allow". If not prompted, use Settings app to disallow Bluetooth for app
After app launches, call await Permissions.CheckStatusAsync<Permissions.Bluetooth>() and response will be PermissionStatus.Granted instead of PermissionStatus.Denied Demo app will put the permission status into the click me button upon being clicked

@ckrutsinger You could try if you also get the issue with the latest MAUI version of 8.0.21: https://github.com/dotnet/maui/discussions/22059

Today I tried on 8.0.21 and 8.0.14. Both still exhibit returning Granted even if Don't Allow is chosen at install. I wonder if the issue has anything to do with the presence of both permission tags in Info.plist:

    <key>NSBluetoothPeripheralUsageDescription</key>
        ...
    <key>NSBluetoothAlwaysUsageDescription</key>

On first launch after install, the app prompts with the string for Always usage. There is no prompt for the now deprecated Peripheral usage permission. So it is the Always usage I am not allowing. Is the permission check returning the Peripheral permission, which apparently doesn't require explicit authorization? await Permissions.CheckStatusAsync<Permissions.Bluetooth>(); doesn't have an option to inquire about the Always permission.

I have added a demo project which replicates the bug on latest MAUI version. See MainPage.xaml.cs

Verified this issue with Visual Studio 17.10 Preview 5 (8.0.21&8.0.7). Can repro on iOS platform with sample project.

ckrutsinger commented 5 months ago

I have retested with MAUI 8.0.40 and issue is still present.

That is a permission check for notifications. This issue is with Bluetooth permissions.
