Have you updated to the latest version of H9 Control? If you go to Settings / About, it will tell you the version number of the app you currently have installed.
when i go to Settings i see H9, but the only options i have are, Location, Microphone, and Use Cellular Data. it offers no version info. fwiw, my iphone is up to date
I meant Settings in H9 Control. It's the button in the lower right hand corner of the screen. The latest version is 2.0.0. If that's not what you have, you need to go into the AppStore and download the latest version oh H9 Control.
