I like a challenge and learning new things. But DJI takes all that away. Somebody please!! I went to the company that makes the equipment and they are not the place to fix or troubleshoot. Equipment P3P same as a lot of frustrated people no connectivity. I probably screwed this one up good. I have followed so many try this try that. If someone is willing to walk me through this issue I promise to pay it forward for sure. I have no connection rc to ac or go app. I have no idea what firmware was last installed on ac or rc.
