Hi there!
As a quick check, are the inputs behind the purple layer on the component view?
If they are, the purple bar is actually demonstrating the areas on the site where this case may happen- see this nifty visual for a better idea of what I’m talking about: https://dev.twitch.tv/docs/extensions/designing/#video-overlay-extensions
If they aren’t, can you send over a quick screenshot?
Also, are you using Hello World or the react boilerplate?
