Pixc: AI Photo Resize

I purchased a subscription to be able to select resizing options. After trying (portrait) a million times, I still saw no change. It would not resize the photos even after uninstall and reinstalling. I really, REALLY looked forward to using this app because I have so many pictures. It was a waste of my money I cannot get back and had the app for less than 2hrs. I wish it worked as stated. Please fix...
