Muy buena pero la función de undo no funciona

I've been using this app for a long time. It's by far the best I've seen. But I just installed it on my new phone and it refuses to access the SD card no matter what I try. I've read other reviews and it's clear the developers don't care once they have your money. Used to be the best gallery app available.

Had it for years then on an update it crashed and was not working g forever I have rediscovered it today and did not get my premium back but it works great for organizing pics and sorting through them rapidly hope the premium can be added again thank you

WHY HAS IT BECOME GLITCHY WITH UPDATES?! The folders are visible in default arrangement, but when I set it to 'Newest Added/Created' , the folders don't show up! They are only visible in the A-Z folder arrangement! Fix that, please!!! Another huge problem is in a lot of folders, I cannot open anything past certain pics! All pics are visible up front in thumbnail view, but when I tap on to open any pic beyond a certain pic, it always opens to that pic and I can't even swipe beyond that pic!!!
