Yesterday I could mute my sound no problem but today it won’t mute, I’ve done an example in this video, as you can see;
volume sound 0 0 doesn’t work
volume sound 1 1 does work but only if the sound is played straight after as it doesn’t work with the pause for a beat in between.
the hell!! 
How this did happen bruhh
Umhh can you try putting the volume beneath the sound and look at your phone previewer? Or else a support ticket ahah
I’ve done all 3 
I was testing out a main menu that I’m using for a story and you can turn the volume off for the story, it was working yesterday and the today it decides not to work.
It’s super glitchy. My menu works like most of the time. Sometimes sound doesn’t mute and sometimes it doesn’t work at all. Now, when I am testing it out, random music was playing when I muted it. So I have no idea what’s going on 
Me either my music still mutes but sound won’t do anything
It’s so annoying. I hope things get fixed soon!
Hopefully
I thought I was the only one with this issue
thankfully not, at least it means it’s not an issue on our end ha ha ha
