Right....the only thing that changed though was a new table and newer android version. However, when I created a new layout from scratch....the auto scroll button had the arrow and the scrolling worked fine. So I think I'm all good, but just for my own trouble shooting knowledge....
1 - original outdated android tablet - layout auto scroll button and manual scroll is fine
2 - same layout but on newer tablet - scale/layout all jacked up, but auto scroll button had arrow.
3 - newer tablet, adapting a layout - auto scroll no arrow or manual scroll ability
4 - newer tablet brand new layout - auto/manual scroll work fine.
I was using the same setlist for all of this, and I always put the bpm/times on my songs when I create them.
