I cannot share the screen as the host during a zoom session. I have an ipadpro OS15.2. All I get is a black screen with the words, "You are sharing screen" and "Share Device Audio: On." I've tried updating the OS, updating (and uninstalling/reinstalling) zoom. Tested it on and off wireless network. It works from other devices, but does not work with this ipadpro (which I need to use for various reasons).
