Opened this app after a while of not using to find the features completely changed. The sky no longer moves with my camera and instead shows the night sky from a space perspective. I have to move manually. I paid the $3 because I really liked the old version, but it only added more things for me to look at. It didn't fix my orientation problem. What am I missing? Is this a setting issue?

10 to 5 on a -2 morning very clear skies above north Nottingham, and this app can not find the moon that is visible to everyone and can't find the Plough (stars not the pub) easy to see why it's free to install. Sometimes it sends you a notification about something but doesn't say what it is your meant to be looking for, it can't see th moon so no chance seeing anything else..I'm disappointed to be honest with this Star tracker. 😕

Nags too much, When I try to use it just as I get to what I want it pops up to ask me if I want to enable notifications. this is very annoying because I have to tell it to dismiss before I can go back to what I was doing. this app is quite often being held with one hand overhead when this happens.
