So, I've downloaded the app on my Android phone. It doesn't work without giving up your location service, and then it wants access to storage with all of your photos and videos, otherwise it wouldn't open. I gave it a permission to storage  by accident and then I couldn't delete any personal photos from the app after???
Basically all of my 1000's of personal photos from the phone ended up in their hands without possiblity of having them deleted.

TO make things worst, the video that I tried to transfer from the OSMO Action camera didn't get transffered.  
This is a horrible app and company is way to invasive.. Last time I buy anything from DJI.

Hi  VT_Ski
sorry for the inconvenience and I think it is misleading for the delete photo part.

plz refer to this video for transfer footages:

The mimo app "+" is to select footage on the phone and to editing.（so no deleting...）

plz let me know is above does not help.
