PhotoPermission always starts at 'unknown' and is therefore never requested

Bug Information

Version Number of Plugin: 5.0-beta
Device Tested On: iPhone/iPad (both iOS 12)
Version of Xamarin: 4.0

Steps to reproduce the Behavior

Try to request Photos permissions on ios:

cameraStatus = await CrossPermissions.Current.RequestPermissionAsync<PhotosPermission>().ConfigureAwait(false);

It will return unknown always.
Also, checking it returns unknown always:

await CrossPermissions.Current.CheckPermissionStatusAsync<PhotosPermission>().ConfigureAwait(false)

This is because https://github.com/jamesmontemagno/PermissionsPlugin/blob/master/src/Plugin.Permissions/Permissions.ios.cs#L413 checks for unknown in RequestPhotosPermission() and then returns unknown without trying a request.

I created my own 'ForceRequestPhotosPermission' in my ios project, with the same code as in Permissions.ios.cs RequestPhotosPermission() but without the check for unknown. Everything works like a charm then. After approve or deny, the status is never unknown again

The same can be said about the Camera permission.

Version Number of Plugin: 3.0.0.12
Device Tested On: Android Pie on emulator.
Version of Xamarin: 4.0

Edit: I forgot to put this line in my activity, to get the result:

Plugin.Permissions.PermissionsImplementation.Current.OnRequestPermissionsResult(requestCode, permissions, grantResults);

And this line in the AssemblyInfo.cs:

[assembly: UsesPermission(Android.Manifest.Permission.Camera)]

It's working normally now.

This says if it is Unknown (which is the default) then request it. That code works as expected from all of my tests.....

My bad, I read the Permissions.ios.cs line 413 too fast I guess. It checks for != unknown
Very strange though that it doesn't work when using your library call for this in my project, but when I remove the check for unknown, and just request it, it works :(

I'll give it another quick debug through and check.

We are seeing this issue as well.

Everything has been working well for the last 6-months+ however after updating to the latest nugets for XF, Permissions, MediaPlugin etc the permissions are no longer working.
