We've had the night sky app for about 2 months give or take and suddenly it has stopped working. The app only allows you to view the direction east, no matter where you are looking. Also, the app 'ISS Spotter' is also not working, with both of these apps it seems to be because of issues with location, but the location setting is on. I'm not sure if this is relevant but the email on the iPad is also not allowing us to send or receive new emails. Is this an iPad problem or to do with my wifi but all other aspects of the Internet are working.
