Excited to get the DJI email re: the new Matrice 100 firmware and Guidance firmware - both installed (finally) and it's up-and-running.  A question - at the bottom of the email (Notes section at the bottom) it says the new firmware must be used with the "N1 Flight Controller Firmware 3.1.5 or above".  I assume the flight controller and the transmitter are the same thing.

The only way I've found to update the transmitter is to hook up my Android, run the DJI GO app, and let the home screen tell me if I need an upgrade or not.  If I do, I walk through the steps to do this.  If I'm on the latest version, nothing is required.  So - how can I check to see which version I'm using?  I swear I've been through every screen on the GO app and can't figure it out.  ANy ideas?

You can check the firmware version in the DJI GO app->general settings->About.
