power cycling the iPad solved the problem.
Awesome. That's great.
We had tested the app on an iPad 1 before submitting it to Apple. So, I was surprised to hear that there was some sort of problem on an iPad 1.
I apologize for correcting your usage of 'crashing'. That was a bit snarky… I just misunderstood the problem based on your initial description of it, and I was worried for a bit that we might have made a mistake in the way we built the app before we submitted it to Apple.
