My Mini SE drone is failing to connect with my iphone SE and I read they're not compatible

Hello there Julian JJ. Good day and thank you for the inquiry. After checking the mobile device ( iPhone SE ) that you want to use on the DJI Fly application and on the DJI Mini SE. I am sorry to say that the mobile device is not yet recommended for the DJI application. DJI suggests using a recommended mobile device for the DJI Fly application for compatibility and reliability purposes. There is a possibility that the iPhone SE will be able to work on the DJI Fly application. But however, since it's not yet optimized with the said DJI application we cannot guaranteed if it will work all the time and if it will be able to run all the functions of the DJI Fly application while using it. For reference I will post a link where in you can check the recommended mobile devices for the DJI Fly application ( https://www.dji.com/downloads/djiapp/dji-fly ). Thank you.
