I recently bought a mavic mini and had a couple of flights now. For some reason none of the photos I have taken have stored and only some videos. Also, it is only records for around 15-20 seconds. I have tried switching phone caching off, recording in 1080p at 30fps and even re-formatted my 64gb card and made 40gb space on my phone, but I still cannot record for longer. Has anyone else had these issues?
