### 1/5 — Black screen

*2021-02-08*

The app doesn’t work. I want to scan the card we received but it gives me a black screen and nothing to be seen. I can hear sounds but no image. Such a shame.

### 1/5 — App doesn’t work

*2020-12-19*

I’ve tried to figure out how to get this to work, and it won’t Register at all. The screen just stays black even though I’ve given permission to use my camera.
