PDF Max App Reviews

I used the app for long time, but it crashed on the last update on my iphone and I have no access to my library which was so critical to me anymore on my ipad! The last update seems awful, fix the problem plz

I paid for this app and I cant get it to load on my iPad Air. It load for 5 secs and it disappear. Please let me know what to do.

Just letting people know as it seems like false advertising. The free version is basically just a reader.
