Hello! No notifications about messages and incoming calls from iOS app. If I delete app, or exit from account and login again (not always help), it works fine few hours or days, then stops working again.
I use my own TURN & STUN servers, but test it with standard servers and without it.
iOS version13.5.1 (tested on many different phones & iOS versions)
iOS app version 9.0.1
server-sde version 8.0.10
Nextcloud version 18.0.4 (tested on 2 different servers 18.0.x)
