Waiting for my employer to approve it. iOS 10 crashes some of our internal apps. If history is any guide, it will be another couple of weeks. Of course, I'm getting an iPhone 7 so will be upgrading before we're ready to go. At least our internal apps are just for convenience (they replicate things we can do on our notebooks).
Your employer should have been testing their Apps the past 2 months while on the beta version of iOS 10, and especially the last week when the GM dropped.
