Longman is the best dictionary for learners, but it doesnt work on iOS 9. Developers must update an app before the release of a new system, not after.
Also, I would like to say that you, Pearson Team, have always done an unserious job.
The design is still ancient, search correction suggests strange and nonexistent words, and now you cannot update your app in time.
We live in the digitalized world, when everyone uses the dictionary in a smartphone or a tablet. If you dont start focusing on your app, people will just forget about you and begin using another dictionaries. Please realise that, before its too late.
