Use it regularly.. kinda begrudgingly

Listen I NEED this app for my photography business. It’s so awesome for knowing the sun’s angle & how soon it tucks. But I am beyond annoyed when I have to use it because there has got to be a better way to use the coordinates feature. I loathe the fact that I have to copy them from Google, then paste them elsewhere and separate them out then paste them into the app. Please, for the love of all that is good.. fix this feature.

Latest update broke it

Fantastic app but sadly the latest update completely broke it. No AR or camera feed on iPhone 14 Pro, latest software. Tried reinstalling the app but no luck.
