Workaround: you can retrieve application identifier on UWP by using this code:

static string GetApplicationIdentifierWithUWPWorkaround()
{
#if UNITY_WSA && ENABLE_WINMD_SUPPORT
return Windows.ApplicationModel.Package.Id.Name;
#else
return Application.identifier;
#endif
}
Resolution Note (fix version 2022.1):

Fixed in 2022.1.0f1

For anyone who wants to use the workaround, in my Unity version (2021.2.13f1) I had to change
return Windows.ApplicationModel.Package.Id.Name
to
return Windows.ApplicationModel.Package.Current.Id.Name;
in order to make it work.
Thanks for providing it!

Hey @peachypixels,

we don't plan to backport this to 2020 & 2021 simply because it was never implemented on UWP and it was treated as a new feature. However, I added a workaround you can use in 2020.3 & 2021.3 in the resolution notes.

It would be great if this could be fixed in 2020 & 2021 as well. Thank you!
