Known issue: In iOS 10, Apple has changed the concept of how applications are called from the background. This is now being done via push notification which is not a feature currently supported by VidyoMobile. The determination at this point is that this feature will be developed with the VidyoNeo for mobile product line.
Workaround: Use VidyoMobile for iOS in the foreground.
Vidyo issue: VMiOS-3004, VMiOS-3079, VMiOS-3127
