Today after i got back from 3 great flights...i got on my WiFi and got the Dji App up and My flight record  and i tapped to sync the flight recoreds and i got a screen that said they had     Failed to synchronize....whats wrong here WiFi is connected so ?

If that is 'the only' issue i would think it is just the servers at DJI that has a problem, they often have, try a little later and later and the next day....
It is when your old flight records begin vanish out of nowhere it get problematic, see this thread and the follow up thread.

I had the same issue, they seemed to be working now

same here tried four times yesterday , waited an hour or so and then it worked

Could be problems with dji server

Hi There,
                 Mine was not synchronising recently and I did not realise I had my drone for over a month, time flies...
So when I altered the time to synchronise from a month to 6 months all was fine.
