Offline on a plane and unable to make adjustments. I was sitting on a plane for 4 hours and had my iPad. I discovered that I could only make rating and check mark adjustments to my pictures. I made sure they were in sync and on my iPad before I left. I figured I could play with sliders and see do some experiments. Nope. Waste of three hours of experiment time. I will stick with Lightroom classic on my laptop once again. I travel and I am in low or no bandwidth places often enough and there is considerable downtime. Seems like an easy thing that should work.
