Thank you for your response. Just trying it now. I also opened a ticket with sixbit ticket asking the same question. Here is their answer:
“Hi Akbar,
The mobile friendly code is automatically added to the HTML when SixBit submits listings to eBay. Please let us know if you have any other questions.
Thank you, Dustin Sherburne SixBit Support”
Afterwards I went to the eBay listing and tried to revise the description. Upon clicking the mobile friendly hyperlink, i got these results as shown in the attached picture.
