Android user's camera stops when a web user joins the meeting

Description

The camera of the Android user stops (while active) for other users in the meeting when a user joins from the web.

Expected Behavior

The Android user's camera should work normally when a user joins the meeting from the web.

Steps to Reproduce

User 1 joins the meeting via iOS app and turns on the camera.
User 2 joins the meeting via Android app and turns on the camera. -> Works as expected.
User 3 joins the meeting via the web and keeps their camera off. -> User 2's camera stops working, and both User 1 and User 3 cannot see User 2’s camera.

Environment

I am hosting my own Jitsi Meet server with custom configurations.
jitsi_meet_flutter_sdk: ^10.1.2

Error Logs

I debugged the issue on User1 iOS and found the following logs when User 2’s camera stopped working:

Solutions Attempted

I tested the example provided in the library (https://github.com/jitsi/jitsi-meet-flutter-sdk/tree/main/example), and it works as expected.
I tried changing the order of steps to reproduce the issue and confirmed the problem only occurs with Android users.

Question

I noticed differences between the config.js files on my server and Jitsi’s default server. Could these differences be causing the issue? config js server (seft host).txt config js server jitsi.txt
