Today is release day for iOS 9 (10 a.m. PST), which means (1) Apple’s servers will probably be slammed all day and it could take a long time to download and install the update, and (2) not all third-party apps are ready for the new operating system.
Before you apply the free upgrade, make sure any apps you rely on work properly. So far I’ve seen updates to ShutterSnitch, The Photographer’s Ephemeris, Handy Photo, and Flickr, to name a few photo-related apps. Others may already work fine with iOS 9 without a special update. And at least two are specifically not ready yet: CamRanger and Fujifilm Cam Remote.
iOS 9 is released tomorrow, please hold off on updating your iPhone/iPad as some CamRanger features will not work. Check back in a week.

I’ve been running iOS 9 betas for several weeks with few issues, but it’s always good to be cautious right when major new operating systems are sent to the wider world. Be sure to make an encrypted backup via iTunes before you update; that retains a lot of passwords and other information that you’d otherwise have to provide during the update process.
