New user. Bought new Mavic mini. Flew it once. Tried to connect later and didn’t work. Tried again with research and getting a moderately red blinking light. Battery’s are fully charged. Connected drone to controller but none of the buttons work. After going from yellow rapid blinking light, went to moderate green for like 2 blinks, then immediately to moderate red. Drone will not connect to app. I have an iPhone 7+ running iOS 14 and DJI fly is running 1.2.1. Can’t find any help online. Thanks.
