I don’t know if it’s just me, but I was watching Robot Wars in the Gizmoplex theatre, but I missed part of it and I was trying to rewind, but I accidentally hit the mute button, and it won’t unmute. I have tried multiple times. I tried going out of the theatre and going back in, but it still won’t unmute. A momentary glitch? I don’t know.
I’m on a Lenovo ThinkPad, Windows 10, using Chrome.
If in doubt , refresh the page, restart the browser, reboot the pc/laptop and if all that fails, resort to voodoo 
I’m going to try again tomorrow and see what happens. 
So I tried today and I couldn’t click on the volume button to unmute it, but when I had it highlighted with my mouse, I was able to unmute it with my arrow keys. This still seems like an issue even if I got it to work. I should be able to push the button to mute or unmute.
Weird. Does sound like the mouse click is not registering, but I’m guessing clicking elsewhere works? Ie full screen, play/pause etc?
Can you try it in an incognito tab also? Ctrl + shift + n , if you’re still using Chrome. Just to see if it reacts differently.
Everything else worked. And I tried it in an incognito tab just now and it worked. So I went back to the regular tab and this time, it worked, but it was not working before. I don’t know what made the difference, but it definitely wasn’t before. So perhaps it was just a glitch on my computer. I don’t know.
If it works in incognito mode, it may be a chrome extension also. If you use ad block or something, might try to switch it off for the gizmoplex. Might just b a one off but least there’s a workaround if needed again 
Yes, that’s a good thing. It’s always nice to have a backup. Thanks for the suggestion!
Happy to help
