Hyperion 3

Works as it should, downloaded and updated my Hyperion 3 for the Nintendo switch 2.

Needs Work

There’s a banner at the top of the app that obscures the menu bar. Not sure who thought that was a good idea. Controller customization works as it should when the menus are accessible and readable. It’s be great if some updates were made to improve the UI and usability.
