I'm using a Nexus 5x. I'm using the 3.5 app.

I have purchased the character sheet and dm tools.
I have downloaded all the official content here plus gashran's feats including psionics and iron Will.

When adding a racial trait level in the character sheet, it crashes. Incredibly annoying, as for this character, I cannot use the app.

Finding and downloading all the extra content was a bit more involved than I had hoped. Should have an option to add things in the app, at least official ones.
