PS4 Dual Shock Controller No Longer Pairs

I purchased a PS4 Dual Shock controller at the Apple Store earlier this year. It worked fine with my iPad Pro for a while. Then, I tried pairing it with my new iMac. From that point forward, the controller did not work on either of my devices. I have forgotten the device from both the iPad and iMac, reset the controller (pinhole on back), upgraded my iOS and MacOS, and scoured forums looking for solutions. It appears I am not the only one experiencing this. It is very frustrating as I subscribe to Apple Arcade and haven’t been able to play with the controller for a few months now.

The current situation: when attempting to pair the Dual Shock controller with the iPad or iMac, it doesn’t even show up on the Apple device’s Bluetooth screen.

Any help is appreciated.
