Native Alerts and VoiceOver

Our game makes use of system alerts launched on top of Unity, to show important texts that we want to work with the system's VoiceOver feature. This has been working on iOS but on macOS the VoiceOver does not seem to want to read the alerts.

We've tried everything we can think of and filed it as a bug report.

Wondered if anyone else can confirm or deny that their native popups don't work with VoiceOver? We don't want to have to go down the route of implementing our own in-game text-reader if we don't have to.

 

How are you doing system alerts? This is not a Unity feature.

 

With a native plugin that we've written. Sure, it's not a Unity feature to show native alerts but it's a feature to support authoring these kind of plugins. Our suspicion is that it's something with the way the Unity player is authored on macOS that blocks the system VoiceOver, so it's out of our hands.
