I recently bought a 2023 A4 35TFSI. I downloaded the app which I've used several times. However, today I saw "unlock/lock your car" . I thought I'd try it so hit the button. It asked for my pin, which i typed in. It didn't unlock the car, and the app is stuck on the page with the Audi symbol coming and going on the screen. I can't use the back button or "forgot password " button. In fact can't get into the app at all other than the screen which it's stuck on. What's going on?
