some of my friends using Android 9.
There is the big problem with missing notifications.
I have tested the current version 0.960.0 on Android 9 and it works great.
So it seems this big issue is fixed in this version (and also a few smal issues).
So I think it would be great to release this version in Play Store very soon.
Of course still as preview.
My friends and I would be very glad.
