I am Oversea in Russia. After the fly from USA to here, I founded the RU Customs notice Tag of searching check in my Suitcase with my DJIP4P+. When at Hotel, by turning on my unit I founded an unexpected problem as my P4P+ not even connected with the Go4App as it do not run even say Connected. At beginning was only missed the video feed, but after reset from factory won’t even open the app. I am able to fly the Drone but the App when pressing the “GoFly” button don’t do anything. 

I been trough the following troubleshooting:

- Latest Firewire updates Remote & Drone
- Downgrade of Remote & Drone firewires
- Factory Reset from the Remote

Can anyone help me or anyone has same issues solved?
