Black screen during screen sharing

[noelow]

Someone hosted a Zoom meeting and I joined via Zoom on web on my computer. I'm unable to use screen sharing and view the screen of the participant sharing but my mobile (Zoom app installed) has no issues.

Is screen sharing and viewing of the screen not allowed in Zoom on web?

Can someone help? Thanks!
