Q&A widget does not open for host

It sounds like a frustrating issue, especially as the host. Since attendees and co-hosts could use the Q&A normally, it might be related to a temporary connection issue between the client and Zoom’s servers. You could try signing out of the Zoom app and signing back in, checking firewall or network restrictions, or testing from the web client or another device. If the problem continues, it may be best to contact Zoom support with the webinar logs so they can investigate further.

hi ​@Paulette E ,

that does not sound like normal practice. You should be able to click on the q&a button and see the outstanding questions. 
For me the widget pops up but at the top, the words connecting and disconnected keep alternating.
this sounds like the app is having problems drawing its screens, How powerful is your machine, did you have screen sharing or other apps in progress?

I would try running a webinar without an audiece - let me know how it goes.
