### 2/5 — Viewing area is always black!

*2023-03-16*

What a cool and useful visualizer idea!  Such great previews!
But when I launch the app the main viewing area is always black, except for the 3 switches.  Tried iPads, iPhones, dark and light modes.  Is there ANY setting where the visualizer is visible?  
Awaiting an answer or update, hoping to raise rather than lower my Star rating, please…
