I have the same issue. Waves or no waves it still vibrates. But thanks for fixing the push notifications!

I finally have "notifications"! No push alerts, but they do show up under the notifications tab... That's a start!

I just installed CNBC app. Crazy how it's been 3 months and only gotten worse, not better.

Now I don't get notifications regardless if battery optimization is on or off. 

so it's been about three this ever going to get fixed?

This somewhat works. Disabling Battery Optimization on Pixel for seeking alpha app allows for notifications to populate.  However, you actually don't receive notifications- you have to manually check.

Google Pixel 1 running Android 8.1.0 with app 4.15.8

Was originally a beta tester user, but the issue persists in the regular version as well as the beta...
