Sorry for the delayed response.... I've had multiple Anafi issues in the past week and all this raises further questions!!
(To be brief, Anafi #1 - just 6 weeks old - developed a gimbal problem after about 60 flights. Parrot agreed it could be exchanged for a new one, but had to be done via the online retailer, hence sent back to them. New one - Anafi #2 - arrived and seemed fine but after one flight (without incident) I got the 'vertical camera error' message and, somewhat strangely, from then on the main camera stopped working. No photos or video possible! Not sure if related to vertical camera or not, but anyway, I sent it straight back and now have Anafi #3)
so... Anafi #3 - all working well so far, and had reinstalled FF6 on my Android phone as part of previous troubleshooting. Was pleased to see that after entering my account details it showed the flight data from Anafi #1 and #2 - good! Also in the drone section of the app, the number of flights and last flight duration only relate to current drone - also good.
BUT ... today I have made 4 flights (these are flights 11,12,13 & 14 with Anafi #3) and only flight 12 shows in the app! The other 3 were much longer and are being ignored by the app. However in the drone section the last flight duration appears to relate to the actual true last flight (flight 14) and the total looks correct too. So, how is the app ignoring 3 of today's flights?
Onto the questions.... (if you can help)
- When you said you had examples where some of your flights didn't show up for a couple of days, did you have some new flights during those couple of days?
- Did all the missing flights eventually show up?
- Do you know if you format the SD card (I now need to as mine is close to being full) would that maybe mean any chance of the missing flights showing up is lost?
- When you request your flight data from Parrot, do you know if they might have these missing flights saved, or do they only have the same .json files we see in the app?
Finally a couple of pics from Glen Douglas near Loch Lomond where I was flying today. A beautiful place with almost no people
