I have 2 solos and an iPhone 7 and after doing a new update I can't connect either controller to the app . All I get on the app now is a connect button and when you push it it goes to the screen that says to turn on the wifi and put in the password sololink etc . The controller connects to the drone fine . I have tried doing a factory reset and nothing works . Did something change in the new update and how do I fix this .
