Remote app on iPad no longer rotates after upgrade to iOS 7

I love Remote, use on both my iPhone and iPad. However, after upgrading the iPad to iOS 7, the app no longer rotates to horizontal view - in fact, it doesn't rotate at all. Bad enough no horizontal, but to not rotate at all means that I can't orient my iPad angled up, while having the power cord plugged in at the bottom?

Seems so strange that this would be changed - why? Maybe I need to re-install?

Help.

Thanks,

Bruce
