Used to love it. Needs bug fixes

I have been experiencing the app closing every time I try to go back to my camera roll after working with one photo. Right now the distance to home skin is using my current location and not the GPS from the photo. It gets the name right but the distance is way off and the same for every photo no matter what country I took it in. The developer asked for feedback but I cannot find any way to do that other than give a review. Please make it work like the last version I had no issues with that version. Can I downgrade?
