Hi,
If the camera video recordings are saved to the SD card successfully but do not display until restarting the camera, it's suggested to try to remove the SD card from the camera and insert it into the camera again, then check if the video recordings will show up on the Tapo app.

You can also try to insert a different SD card into the camera and check if it will work fine if you have one.

Best Regards
