But
Ashley next year is it still possible to launch app to test export on MacOs ? Or to each test it will must be notarized to launch ? https://developer.apple.com/news/?id=09032019a
See the tutorial I linked to previously. It describes how to test without notarizing.
Wouldn't that mean that Multiplayer games could break when minimized or is that working independently, regardless of that callback?
Currently we use a hack to keep multiplayer hosts alive while minimized, but I expect browsers will break that sooner or later as they more strictly impose freezing on background pages, since it's critical to save battery life.
