I agree with all the comments that we need a better experience for iPad Pro. A feature that would be nice would be for tags to be nested like on Windows. Also, I have a terrible time executing searches on the iPad and many of my saved searches (created on Windows) don't work.
But the issue with not being able to check check boxes is the WORST! I keep poking at various spots on the screen hoping that the box I need will be checked, but 9 times out of 10 I give up and hope I remember to go back and check a box on my computer later. Ugh!
