I have been testing the new Canvas Teacher app, and I just don't get notifications for new messages in my inbox. I do get the notifications on e-mail. I have verified that the notification settings for new messages are the same for e-mail and push in Canvas (website).
Since this is a crucial feature, I assume something is wrong on my side. But what? I'm running Nexus 5X, i.e., using the Android version of the app.
