### 1/5 — It’s working?

*2023-10-22*

I can’t pass the permissions screen. 
Motion seems that doesn’t accept permission

### 1/5 — Buttons do not work

*2023-05-24*

The ap will not allow me to click the allowed buttons to continue.

### 2/5 — Troubles downloading and working

*2023-04-24*

I was able to download this, was even able to get the camera and motion to be allowed like in the YouTube Vedic but I am not allowed to do the microphone at all. I have done everything the developers have told me to do for it to be able to work and still nothing. Only emails to tell me to let my child on the app and not away to help me to be able to use the app.

### 5/5 — Excelente

*2022-10-14*

Great study for my sons*
