So i just recived my mini pro3 with the rc remote and trying to set it up and it will not connect to wifi. Please help

Make sure it is charged up to at least 50%.  Start the Fly App and go through the prompts to set up the controller and activation.  One of the early steps will ask you to set up your wifi connection to include your password.  If you have already done this then open the Fly App and scroll down from the top and you'll see the settings.  Be sure wifi is turned on.
