Hi, I have been using a Tapo C210 camera and recording using SanDisk High Endurance micro SD without issues. 
However, when I take out the SD card insert it into my PC through a USB with the adapter which came with it, my PC says please insert drive. The drive is not readable. I have tried other devices that can read the SD card adapter through USB, and all show that there's nothing on the drive and cannot be read. I have also adjusted autoplay settings on my PC and it does not make a difference.
When i place it back into the camera, i can view the videos through the Tapo app without issue and have downloaded 1-2 videos from the app into my phone without issue.
Please help, thanks!
