I updated the program selection now and should work everywhere, including iOS! This is for the program preview. If you select the program it will redirect you to the change program window and expand the specific program you selected allowing you to edit it. Minor feature but a nice shortcut.
I also fixed the problem with Android being unable to navigate the timeline/preview. The fix is indirect but I added a navigation menu on the bottom right with a move right/left and zoom in/out button. Tested it on Android and seems to be working well.
Loving the preview page now, thanks for all the feedback!
