Pain Points
Absolutely unusable. just spins and spins.
App crashes every single time i use it.
Need to fix the pictures uploading at the wrong orientation problem that has been going on for literal YEARS now.
I do with the photos would load in right side up so I didn't have to rotate every single one.
