Crash loading model

Well, that was pretty disappointing. First time I try SketchUp for iPad and it won’t even load my model. Just crashes. Every time. No error warnings, no nothing, just crashes hard. The model I’m trying to load is 76MB. Not small, but certainly not big as SketchUp models go.

Any advice? I mean, any ideas other than trying to downsize the model, which is impossible. I already follow all the guidelines I can find for minimizing model size because of large-model performance degradation on my Mac.
