Mobile App version 20.6.0 build 101
When trying to connect to on-premise Jitsi installation and to https://meet.jit.si from a phone (iOS and Android) with two sim cards (two numbers, two Internet connections) application does not establish a video/audio connection. It tries to connect for 30s then hangs up.
On same configuration (phone with two sim cards) web-based application works good.
After turning on wifi connection mobile app works OK.
Switching off one of the sim cards resolves the problem, mobile app works OK.
I have tested this issue on multiple iPhones and Android-based phones. Every time it doesn’t work.
