It has been a couple years since i have operated my drones (Mavic 2 Zoom/Phantom 4 Pro) I have upgraded my mobile device and now cannot get my controllers to respond to connect to the phone or drone? Can anyone provide some insight? (iPhone 14 or iPhone 15 Pro max).

Have you checked the supported devices list on the download page?  If not, you can check here:

Thanks, yes I did check device compatibility. I cannot believe they have not updated devices. I swear I used it with my 12 Pro max and it is not on the list of devices.

I think there are several devices that work but just haven't been checked by DJI for full compatibility so they aren't on the list.  

Finally got connected via usb… first flight in a long time.
Made it 3 minutes in and lost all video and control.
Controller and app showed disconnected so I had to wait for the battery to die before retrieving drone!?
