After setting the name and title in a name tag and then close the VCam app, the next time I start VCam the name tag is blank.
It also seems to clear my name tag after taking a video call.
I set the name tag up, minimized VCam, and then took a Teams call. When I hung up my Teams call, my name tag was gone again.
I have tried setting it in both the app and on the website.
