If you go to a device in the companion app and want to edit a scene from there, the browser is opened and the companion app is exited.
As shown in the screenshots, the "Ceiling Office" device has been selected in the app and a scene is clicked from there: The browser opens. This is just an example to make it clear what I mean.
The same happens when automations are called up from the device.
I'm not entirely sure, but I think this has only been the case since 2025.3.3.
