Phantom 3 Advanced Controller not Linking to iPhone/iPad

Decided to get my old drone out of storage and fire it up. However, there seems to be an issue. The iPhone 17 nor the iPad mini 4 will connect to the controller. The controller just blinks the red light and beeps loudly. The DJI Go app just shows the “How to Connect” button and never shows a button to connect to camera.

iPhone 17 iOS 26.4.2

iPad Mini 4 iPadOS 15.8.7

DJI Go app v3.1.81 (3060)

DJI Controller version - No Idea

DJI Phantom version - No Idea
