I'm #XMPP #Conversations user with our own server
Recently one family member changed they mobile device and since then have had many Push #Notification Issues
Only this device is affected (xiaomi OS), so i did not messed with server configs.
Now reading "How do XEP-0357: Push Notifications work?" https://codeberg.org/iNPUTmice/Conversations#how-do-xep-0357-push-notifications-work and
"Conversations Push Proxy"
https://github.com/iNPUTmice/p2/blob/master/README.md
I'll will install google's play store version and wait it has some effect on the issue
