Has anyone experienced this issue with the Phantom 4 Pro+, I have the drone up to date through DJI Assistant app but it will not connect or pair with the remote. I've tried linking the remote, doing the c1, c2 and a few other steps listed on the DJI website along with linking through the app and holding down the button for 2 seconds. I've tried refreshing the up to date software many times, reset the remote but still am having no luck connecting. The remote says firmwares up to date.


Conclusion:
Issue Resolved, after talking with support I learned the remote software was not up to date although it did say firmware up to date when I checked it earler. I believe this was because of poor wifi connection but not sure.

As per the video (if you've not watched it you should ) ... upgrade the aircraft firmware...

Glad to hear you have got it sorted out and thanks for sharing with us.
To ensure it's upgraded successfully, it's better to check the numbers on "About" page through the APP.
