www.pbskids.org / The app has been installed in wrong way
My kid started to play on the website www.pbskids.org. He liked it so much, but I needed the access to the computer, so I decided to install the app. I downloaded the app and installed, but it showed that the app wasn’t installed properly and couldn’t be open. I tried to delete it, but nothing. I also sent emails to the website’s owners, but they didn’t react. I have no idea what to do now.
