I am having a problem with panorama when  controller and iPhone is not linked to drone it does show the panorama and other options( like shallow focus) but when phone and controller are linked panorama and shallow focus do not show the only option it shows is single shot or video

I have exactly the same problem, did u find a solution?

Make sure that you have installed the latest firmware on your drone and remote controller and the latest DJI GO 4 mobile app in order to use the 180° Pano mode. Once you have updated the firmware and the DJI GO 4 app, you will be able to select the 180° mode under the Pano mode and start shooting.

Stitch Photos into Panoramas
After you finish your panoramic photo shooting, you can tap the playback button to check photos. By tapping the photo you’ve captured, DJI GO 4 will automatically stitch them into a panoramic photo. Don’t disconnect the aircraft while stitching because your phone needs to download photos from the aircraft. After it’s done, click the download button, the panoramic photo will automatically be saved to your phone.

If you want a high-resolution photo, you can use DJI Media Maker or other stitching software to easily stitch RAW images into a panorama.

It should be noted that when the aircraft’s GPS signal is weak, the surface texture is not clear or when it’s in strong wind, the aircraft may not perform precision hovering. This might affect the stitching quality.
