Disappointed

I got this app about 2 years ago and I loved it! Used it very often to identify planets and their positions. Very interesting!
Opened it several times in the last few months, deleted and reinstalled it twice, and cannot even use it anymore because it jumps around as I move it across the sky, and is no where close to accurate!
I point it right at the moon, and theres no moon on the map. Try to adjust it and it jumps all over and jerks back to same location, that Im not even viewing!
Im so very disappointed, as I really loved the app. Im deleting it now, but will check back later to see if the bugs have been fixed! Hopefully, it will be fixed soon!!??
