I have a problem of exporting music files to dji fly local recently. In the past, I can export large music files from dropbox to dji fly local. But recently, when I export music files, I found that any music files larger than 40M could not get through. When I did so, dji fly said "unable to transfer music files over 40M". Any solutions if i want to upload files larger than 40M?
