Solved iOS 3CX application not receiving calls but WebClient can

[zedsd]

The 3CX app was installed on 2 iOS devices (both versions are greater than 15) but neither can receive calls. They can make them without any issue & receiving calls from the WebClient works. The 3CX instance runs version 18 & is self hosted with a public IP address & the firewall reports no issues (including any APN ports). PUSH notifications have been enabled & various combinations of settings have been attempted to no avail. Is there any particular procedure required to support iOS receiving calls or perhaps an upgraded license (I am on the free version)? Thank you for your time.

This can be expected as you need to be on the latest update for the certificates:

Updating 3CX solved the problem, thank you!
