No notifications on my Samsung galaxy note 10

I installed the ring app and linked it to my Ring 2 Doorbell, but i don't get any notifications. No push, mail or whatsoever. I added another user and she gets messages on het mobile. All sliders are open (blue) and i also checked if the phone allows ring to give messages (and it does). I also tried installing Rapid Ring to see if that works, but also there I don't get any messages.
