Description When going to a room with two devices, we get a warning error, and it does not work.

Steps to reproduce

• Using HUAWEI P20 Pro (model CLT-L29, Android 8.1.0)
• Using iPhone 7 (iOS 11.4)
• Connect to the same room (we used https://appr.tc/r/foobar)
• Get the error

Expected results Seeing the remote video and everything working

Actual results Red warning div with the following text:

We have similar issues with the same HUAWEI and other iPhones.

Can you guide us or explain us what is the issue ? The logs aren't very helpful here.. :)
