Scrolling through my images in grid view in Lightroom Mobile is a horrible UX. The gesture recognition is off -- if I flick to scroll through my images and then place my finger on the grid, the scrolling continues. That is, the only way to stop the momentum-based scrolling is to scroll in the opposite direction. This breaks the UX we're accustomed to with all other iOS apps, and it feels non-native. It's a near deal-breaker for me, considering how clunky this feels.
