uh oh! Thanks for letting me know - I wasn't able to test it on iOS8 - I'll check it out and try to fix it ASAP.

Don't worry too much. The beta releases often contain bugs themselves, and there is a good chance it is not a problem with your app. If you have a chance to test it then you should, but bugs in a beta often get cleaned up by apple with no changes required on your part.

Ah, that makes a lot of sense. Thanks :)
