Stars and moon are off location

This app used to be super accurate and now the moon is 90 degrees to my left when I’m looking at the moon according to the app view. It’s making it very difficult to identify the plants and stars when they are in alignment but I can’t tell via the app which is which as it’s all about 90 degrees off. Please fix this so I and all can accurately identify the plants and stars

Won't launch on my iPhone 11 or screen stays frozen

Bug

The app keeps freezing and doesn't open, even after uninstalling and reinstalling

Bug

Star names not available on screen

Bug

Download the app and nothing is happening?

Bug

This was a gift and I haven't been able to use it since I got it last summer because the app gets stuck on the Leo constellation and does this ticking motion

Bug

I have a AGACS code but it doesn't give me the option o use it to locate my star

Bug

I'm facing south and it has north to the right of me

Bug

Good graphics on the screen. But doesn't match the sky

Bug

Has cool features but all that is lost when I realized it's inaccurate as hell. It has the moon in the absolute opposite side of the sky

Bug

Trying to match up the constellations was not working properly - azimuth was about 120 degrees off, there should have been an easy way to calibrate

Bug

This app crashes quite often
