Screen Sharing Challenge

Hi Everyone - I can't figure out how I lost the ability to share my iPhone and mirror it to my Zoom desktop presentations. I'm on the same Zoom version on mobile and desktop. I'm on the same internet connection as well. When I tap the mirror icon on my phone, it just doesn't find the Zoom meeting any longer. (I have selected sharing on iPhone/iPad / Airplay).
Any help, I'd be grateful!
