In Safari got:

```auto
RoomClient enableWebcam() | failed:Error: a=ssrc line with msid information not found

```

Here the workaround on my side:

Note: Safari now avoids the failing multi-stream legacy simulcast path.

For future occasions could you please report bugs in GitHub rather than here in the forum? Yes, this is a regression and application level workarounds are not the way to go. I can reproduce it and I’m on it. No need to report it (the issue seems to be in mediasoup-client).
