Hi, my push notifications don’t work on my phone, a Samsung Galaxy Note 8, running Android 7.1.1. They work fine on my Android tablet running 6.0.1, a 2nd gen Google Nexus 7. I’ve tried toggling the setting in the app, restarting the phone, etc.
I am currently sporting a note 8 and my notifications work too well! LOL I had to turn them off. Wish I could help, but it seems like you know what your doing if they work on your tablet and nexus 7.
My Samsung Galaxy 8+ is receiving notifications fine. ???
I would try signing out of the app and signing back in. Let me know if that works!
