I love your project @binwiederhier. Lately I have migrated my daily driver from LineageOS to e-os (https://e.foundation/e-os/). Both use microG, but for some Reason I have massive Lag receiving the Push Notifcations on e-os. Seems like it's not really receiving Notifications via Push, but rather via Pull. I'm running my own Instance, however I can rule out that it's a problem on the Server side, as it used to work without any Problems with LineageOS. Do you maybe have any ideas how I could debug that Problem? I've checked the microG app and allowed Push Notifications for ntfy. I've also made sure that Android's Battery Optimization Feature doesn't interfere with ntfy and I got the permanent Notification open (which keeps the ntfy Process running). Of course I've also built my own Android App and I use my own Google Firebase Credentials. I'm kinda lost at the moment, honestly. Would be great if you'd have some ideas how I could figure out what's wrong.
