I hadn't seen this before, but had read of other people's issues with this. Proclaim on my iPad Air (128gb, iOS 8.0.2, current) crashed at least 6 times yesterday during services. Fortunately I had my Logitech remote presenter with me so was able to advance the slides, but it was a little disorienting to have happen. Once, maybe ok... but multiple times like this, not so much.
Otherwise, I think Proclaim functioned ok for us on Sunday - and we had a lot going on - including a downloaded YouTube video that played well.
I think I read that you're working on a new version of the app - can you say when you hope to have it done? I'm reluctant to try a beta version - but is it relatively fully functional yet?
Thanks -
