Hello ,
From my last flights i checked that when i shoot video or intelligent flight mode , the  footage is not available thru the app. I can only see this footage on my pc when i connect the MA. Did anyone else face the same problem? Also with  a class 10 sandisc micro sd the MA says that the card is slow for video recording.

Not 100% sure but what about "Cache during Video shooting" switch in the app.

@AlexPapadas, which SanDisk memory card are you using?

I got the same message when using the Sandisk Ultra 128GB Micro SDXC UHS-I Card with Adapter -  100MB/s U1 A1 - SDSQUAR-128G-GN6MA.  It is a class 10 card.
