Crashes a lot

I use this app constantly. I have logged over a thousand hours on it. It has all the functions I am looking for, but it crashes 70% of the time when I try to open the multi page view. It is very frustrating. I keep hoping they will fix in an update. I even bought the new iPad Air 2 thinking that it might be crashing because my iPad was too slow. I opened the app first thing and it crashed 8 out of ten times I tried to open the multi page view. Worse than before... Very disappointing.
