New P3D owner here. Have a compatible USB drive plugged into the front left USB port. Drive is properly formatted to FAT32 via my mac. Records dashcam videos just fine, but no sentry events. I get the alert on my screen saying there are X number of events. When I plug the drive into my computer, the Dashcam events store in recent or saved just fine, but the SentryClips folder is totally empty. WHAT DO I NEED TO DO DIFFERENTLY?
