Hiring to make dominant speaker works on ios

Hello,

I used https://github.com/jitsi/docker-jitsi-meet to install jitsi on my own server.
I just use the simple configuration in the tutorial.

Then about the mobile app, I used https://github.com/skrafft/react-native-jitsi-meet to embed jitsi in my mobile app. It is also working very well.

The problem here is, the current dominant speaker does not change on ios, only on Android. I don’t know why.
When I change the domain to meet.jit.si, everything works fine.

I think there is a missing configuration in the .env file.
Could you please take a look?

Thank you!
