When I log onto PC and my dashboard there is no place to upload images from most recent mission - also says no flight log available - mission was completed successfully. Saw on other forum threads that may yo need to set permission for that, but have been able to do on other flights.
Make sure your iPad is on the same network as the computer to sync to it so it changes to upload.
You can always use the Upload images button under the plus sign on the lower part of your dashboard to upload/re-upload any images. Just choose Upload Images, name it as you wish and upload as normal. You don’t need to have a flight plan flown to upload.
