Wen't out yesterday with the osmo recording timelapses and videos. Wen't home and none was saved to the memory card? Used the mimo app if that matter. This is really bad since it was footage I really needed for a video. Anyone who had this problem? My memory card is  a high-end sony 64gb. Didnät had this issue the day before.

Can you write to the card on any other device? I mean after this incident?

Something similar happened to me yesterday.  The Mimo app would not display the files but the OP read the files that were saved in the sd card and also my pc read them.  It sounds silly, but have you tried retrieving the files from your pc or from the OP itself?  Somehow the Mimo app didn't read my files and when I reinstalled the app it worked again.  I use Sandisk Extreme Plus 128g cards.  

Same problem here, I'm using osmo mobil 3. It only occurs with the motion timelapse

Is there a solution to this issue?
Have similar issue after timelapse.
