Yes, I'm doing it from a standard app.

It modifies some data in my CoreData. It doesn't modify anything that should change the state of either MyView or PresetPicker. As you can see, there are no State variables in PresetPicker at all.

Replacing NavigationLink with a button worked perfectly for me! I don't even need to add a back button, because I need the back button to redirect me to FirstView, and not to CreateView. Thank you very much, you helped a lot!

Yes, it returned automatically. I would like it to return when I hit back, but it doesn't work that way yet. back to which view? - Back to CreateView.

I expect this behavior: I click on the link in CreateView, it takes me to WaitView, saves the data in the DataManager, and I remain in WaitView. Whenever I want, I click on the "back" link and it takes me back to CreateView. But instead it transfers me back, although this is not written down anywhere.
