I do not get AirBnB notifications instantly when someone messages me but it can be anything from 30 minutes to 6 hours delayed. It seems like this is the only app with this problem, i tried reinstalling the app and also upgrading the OS. I also added the app under "Apps that wont be but to sleep".
When I open the app I get the notification instantly, I'm guess that it goes to sleep somehow when it not open.
This is a very annoying problem as I am a host on Airbnb and guests gets my replies way to late.
What else can I try?
EDIT: I'm in a Samsung S9+ running Android Version 10.
