Hi there, thank you for reaching out. With regards to that, you may use the Wifi module and Yes the adapter that is suggested, then change the format using the Mimo app. Thank you for your support.
Just to add that even if you then come out of Pro mode on the Osmo Pocket, it seems to keep using the last file format you chose for video until you change it via the app again.
The latest update has worked for me. Also the USB C to Micro USB adaptor arrived and has worked. The downside is that it's rather 'wobbly' connected to the phone. A cable version would probably be better as the USB port is on the side of my current phone so not very convenient. I don't plan to record with the phone connected so not a big problem for me.
