Can not start the Fly App Active Track Parallel mode on my Air 2s with Smart Controller. After selecting myself as the object, the green box shows a + and the pop up to select mode is displayed. It defaults to Spotlight so I click on Active Track. It then displays Trace or Parallel. A couple of seconds after clicking on Parallel, it defaults back to Spotlight. No start button or error message. Am I missing a step or option? Any help would be appreciated.

Hi, there. Sorry to hear about this. Please try to reinstall the latest version of the DJI Fly app from our official website to check if the problem persists, note to back up the video/picture files. Here is the link: https://www.dji.com/downloads/djiapp/dji-fly
