ObservableObject doesn't update SwiftUI View

Hi, I am developing a BLE-utilising app. I Have my main SwiftUI View and want to display all the results from my BLE Read in there. Everything works, if I have a button, triggering a view reload after all data has been loading - but I can only know this through debugs...
As I'm using an observableobject, my swiftui view should be updated after setting some @Published-Value to my read-result.

BUT THE VIEW DOESN'T CHANGE!

Here are the most important parts of code:

SwiftUI-View

ObservableObject

NetworkSettings struct + decoder

I would be REALLY happy if someone can help me here - I would be ready with this part but this small problem destroys it for me currently :confounded:

Thanks for any help!
