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

[kietdev123]

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

Are you able to reproduce this on meet.jit.si? Can you please test the latest 10.2 SDK?
