Singularity I have done this and have come to notices that many of my apps do not send notifications If I do. Is there a particular reason play services are needed for notifications?
unwat Singularity What rhinenome said. App servers send notifications to Google first, then Play Services finds the notifications. Servers for different apps don't send notification to your phone directly.
rhinenome I assume without Network access to Google Play Services, it can't connect to Firebase for push notifications
