Prejoin Page doesn't work with Safari Browser and iOS devices

Using the unstable version of jitsi, I enable the prejoinPageEnabled: true function. When I’m using Safari browser on MacOS or iOS, the camera and microphone don’t work, even if enabled.

I can see the participants through Safari but in their browser they don’t see me, it appears as I have my camera and microphone disabled.

I tested it on lobby.jitsi.net and it works normal. I don’t know why in the last unstable version of jitsi it doesn’t work. Can someone help me?
