iOS notifications are flaky while off network

[knob19]

iOS notifications work 100% of the time while I’m on the home network. But while I’m away, some notifications are delivered, and some are not. I have not been able to discern any pattern to which ones are and aren’t.

I’m nowhere close to the daily 500 notification limit (probably well under 100). I don’t use a proxy, DNS, VPN, etc - just an “out of the box” setup. I have AT&T Fiber, and internet connectivity has never been a problem.

These are very basic automations like notify when a door/window opens.

Based on this (old) thread, it would seem that all notifications should be pushed to the phone regardless of whether it is on or off the home network.

Notification are delivered to phone outside network

Hi All, I’m using notify.notify service to deliver some notifications to mobile app. I was surprised today, that I was able to deliver messgaes to phones which are outside of the local network. My HA installation is not exposed externally. There is no way to connect from outside to HA, it has only internet access. How those notifications are being delivered to phones in external network?
