I have experienced a lot of bugs since the upgrade and using my iPhone XS is currently frustrating

After the upgrade I cannot use a lot of the build-in features on my phone. For example I cannot use the top part of my screen. It took ages to open Control Center if I manage at all. It’s the same with all menus that are bring down from the top. I cannot go back to my previous open app by clicking on the left corner.

It’s extremely annoying to use my phone at the moment. When to expect fixes?
