IOS notifications bug

Hello, Blizzard team. I do not receive any notifications on mobile app. And I did when I first started using it few days ago. Iphone 11 with latest OS and latest app version. Please fix this bug, I’m clearly not the only one who has it. My friends struggle with the same thing. By the way there is another issue. When you’re actively chatting messages usually don’t appear correctly. My message may appear on left side of the screen and some of text isn’t visible. Please try to reproduce to see what I’m talking of, I’m sure it’s pretty easy. Thank you in advance.
