No screen option for Share screen

Hi,

When I clicked on the 'Share' button in Zoom. The first option is Photos, icloud drive etc...

I used to have the 'Screen' option right before the Photos option, but now after I switched to 30 days trial on the Pro account, I don't have the 'screen' option anymore.

If anyone encountered with this issue before and resolved it, please provide your solution/guidance. 

Thank you in advance for your help in this matter.

Best,

Leslie

P.S. I configured my Zoom setting on a desktop.
