'Watch with friends' on Metastream via JustChill is not working for me

[3D4S]

I've tried to use 'Watch with friends' on Metastream via JustChill and it doesn't work for me and my friend, we've done it plenty of times, they're able to join the stream, but the show we choose just doesn't work, as in they cannot see what I choose or play but when I press the DJ option they can hear it but nothing else. Any ideas as to why this is happening will be greatly appreciated.
