Just got my Ipad mini 4 on the mail today, which I bought to fly the Spark. Configured everything and as I am flying, the recording keeps stopping on its own. Goes for a few seconds, sometimes minutes and stops. With and without the OTG. Is it a configuration issue on the Ipad? It would seem like a cache limit issue. It's at max (16gb) on the app. Did not have any problems (of this kind) flying with my Android devices. Please advice. Very frustrating.
