I’ve had my Bebop 2 for over 3 years now and haven’t figured out how to get it to show the right year (mine shows numbers like “12827” for the year), date or time. My recall is that this was on everyone’s software update wish list back then - before Parrot cut us hobbyists loose.
I’ve since found a ‘work-around’ on my iOS devices (iPhone and iPad). As soon as I’ve downloaded the photos and videos to the Photo App on the device, I select each “individually” and flip up to expose the input data editing options.
There it allows one to ‘adjust’ the year, date/day and time.
