iPhone app offline mode after skill tree completion

The only lessons that are cached into the phone are those that have yet to be completed. But what happens when one completes their skill tree? (I just did! Yay!)

When your skill tree is complete, the app is no longer functional in offline mode as nothing's cached.

Perhaps cache the least remembered units at that point?

Please, I have the same question. This use to be one of my favorite activities on long flights, but suddenly I can't use the app anymore. I would love to be able to go back and work on areas that are not gold!

I sent feedback in months ago and received no satisfactory reply. Kinda contributed to me no using the app anymore. :/
