Start video meeting in a room has issue, iOS user is not able to join sometimes as loader keeps spinning

### Steps to reproduce

1 out of 4 times i am not able to join the video meeting. I had 1 web user and 1 iPhone user, iPhone user starts video meeting - sometimes it works fine and sometimes it is just stuck, loader keeps spinning with a text "connecting you to your meeting..".

Steps to reproduce this issue -
create a room -> add users (from other platforms also) -> start video call

if you are not able to replicate the issue, try the same thing atleast 3-4 times.

I have tested this on Appstore's element app.

Thank You! hopefully this will be resolved soon.

### Outcome

#### What did you expect?
I expected it to connect me to the video meeting

#### What happened instead?
I am not able to join the meeting sometimes, app gets stuck there is no way to go back but to forcefully close the app, because loader keeps spinning for infinite time
