beta testing

I always sign up for every kind of video game beta testing. So when I got an invitation to beta test the new “BT app” I signed up without hesitation. I was sent a link to download the app. After installing the app, and starting my session, I was asked to take a picture “take picture of subject A”, must be to create my character I thought. I took a picture of myself. Nothing happened. “take picture of subject B”. “mmm… fine…” I sneaked up on my sister and took a picture.
