I just installed ntfy and am going to give that a go for a while and report back!
EDIT: I have been trying to rework my matrix server completely but for the period of time I spun this up for my matrix-dendrite server it completely solved the issue.
So sorry my bad!
The device that struggles with push notifications is a pixel 8 with GrapheneOS. Element was installed through f droid.
Also another problem that I have been facing is I cannot multitask while in a call otherwise it cuts my microphone. I have to stay in app to be able to talk with the person I am in the call with.
Notifications work just fine on my desktop running arch.
I will update the post with this information.
Lemmy wouldn’t let me post it 😭
