I have a Sony XZ with Android 8. Notifications are working fine for all applications - except, for some reason, Twitter.
I want to get sounds for direct messages. A sound is selected. Direct message notification sare enabled in both the app's settings and the system settings for the app, and set to "high priority, make sound". "Do not disturb" is NOT on.
Still, I get no sound and no popup when a Twitter DM arrives.
What can I do to investigate/fix?
