Hi all! Thank you for allowing me to join this site. I have purchase a holy stone 700e, from a previous owner. I have watched some youtube videos, seems like a pretty good drone. I have a problem though; I have paired the drone to the controller, no problem. I have calibrated the drone for horizontal and vertical GPS. All good so far. Now I need to find the holy stone wifi on my phone........now I have a problem. I downloaded the app using the QR code found in the owner's manual. It is the OPHELIA FLY app. The wifi app will not show up on my iphone. Could the previous owner have control because the app is still on his phone? or, is my used purchase a dud? Thank you anyone that can help. SOOOOO frustrated.
