So I found workaround:
1. turn and pair everything
2. run the app, update screen should appear
3. dont run the update, just disable it by clicking on it and stay on the page in the app
4. turn car of, wait unitl the car icon get red in the app
5. turn car on while still on the update page
6. the update page should refresh and tell, that there are no more updates
7. Now there is the back button available in the app in the left top corner, that brings you back to the app.
Note: you need to do this everytime you start the app....
