I have notice that when using my Mavic Air on WiFi. ( virtual joysticks with i phone )  I am able to position the drone with the virtual joysticks. I then select Active Track and start filming..All good ..no problems. When I stop filming and cancel active track, the virtual joysticks have dissappeared and I'm unable to take control of the drone. I guess the activ Track mode isnt quitting. The only solution I have found is to come quit the DJI Go 4 app ( with drone still in the air ), and then restart the DJI Go 4 app, at which point the virtual joysticks appear and I can control the drone again....
Any ideas anyone?

Hi thanks for reaching DJI Forum, we do apologize if you are having issues with the active track mode of your DJI Mavic Air, may we ask what is the mobile device you are using?

I'm using an iPhone 7, OS is current.
