Not sure if I get your question… however, in my application only the “critical” events are the ones that “push” a pop-up notification in the phone … I did not try to change the type of event…
I’ve just checked the latest build from Play Store on Samsung with the same os/oneui versions - pushes are working fine.
On the system settings → there should be “Notifications category” option in the bottom the screen you screenshoted - scroll it a little bit more and tap on that option. It will show device channels (system notification channels’ settings ).
@BlynkAndroidDev I tried the scene automation and the push notification worked… after that, I tried in my application and it worked as well! I did not change anything… but now it is working again… I will continue to monitor if for some reason it will happen again.
I’m not sure if this could also be related to UI updates, as I also noted a few of them has being deployed in my Samsung phone in the past days…
