I can't seem to change my background theme?

I can't seem to change my background theme, I've already tried exiting and joining beta multiple times. On PC by the way, does it work on mobile? 

Thanks

Yes

How to change our background?

Custom themes in settings

Yeah, I got it but I can't change it.

Yeh, then it’s bugged for you as well. Seems to be for everyone

Anyways, thanks for letting me know.

yes i was talking about taht too

it has the boxes where. you would normally change the background but when you click on it the boxes are blank

and after you click the box nothing happens

It's a bug and staff are aware.

that's good, because it's annoying me quite a bit

thanks martin stahl

Yeah, it's working.
