iPhone video problem using the code exchange Basic Video Chat (severless)

[timquek]

I ran the Twilio video chat on my iPhone.
The (severless) video chat is derived from https://www.twilio.com/code-exchange/basic-video-chat

a) From my laptop, I can see the video picture from the iPhone.

b) From my iPhone, I can see the video picture from my laptop.

Here is the iPhone "problem"..... From my iPhone, I CANNOT see the video picture of myself at my iPhone It looks black. (Self View does not work)

However, from my laptop, I am able to see the video picture of myself at my laptop. (This Self View works)

Here is the URL for the video chat

Do you think you can try it from your laptop talking to your iPhone? See if it works or does not work on your iPhone.
I am NOT using Github. I can copy my serverless code in Twilio and email the copy of the code to you.
There are no errors when I deploy the video chat app from Twilio. I am using Nodejs v16 in Twilio.

Thanks for all your help,
Timothy Quek
