I’m not showing in interview meeting room; missed interview.

  I had an interview for an internship on Zoom. The Zoom meeting link was provided before the interview by the host. I clicked the link and joined the meeting room. I was on time and waited 15 minutes past the scheduled start time. My screen displayed what is shown in the attached photo below.

  Apparently, the host joined but couldn’t see me leading me to miss the interview even though I was in the room waiting for the host to start it. What did I do wrong?

Side details-

Used my phone on T-Mobile LTE, the wi-fi was working on my end. Let me know what you guys think, thanks.
