How to delete BBQ theme?

I clicked on the BBQ theme button to see what themes might be possible, and it changed my theme to the BBQ. There's no option to delete the theme anywhere. I am on the free plan. Can someone please tell me how to delete this corny theme and go back to a blank theme so I can actually send this out?

Hi Luke,

you need to click the context menu (three dots) of your PollUnit, then "Edit" and in step "Design" you can choose a theme. You can swipe or click the arrow until you have found a suitable theme. Click "Choose theme" and save your PollUnit.

Best regards
Markus
