Scheduling Attendees list blank

I know. It sucks! What's the point in having a contact list if you can't use it to select who should attend a meeting?

Me as well. It used to do that but no longer does. It's been this way for a while. It suddenly stopped even though my contacts in Zoom are up to date. It is definitely frustrating and disappointing. 

Zoom lets you create meetings it does not automatically add attendees or send emails. You could copy the invite into an email client and send it that way. You could use APIs to trigger an email to your attendees when creating a meeting. There are also scheduling apps that can help you set up Zoom meetings and email your contacts. Looking through the Zoom marketplace one option is Salepager which lets you invite attendees to your Zoom meetings. You could also explore using an email calendar.

Frustrated by this as well.  I spent so much time adding contacts to the personal contact list, and it isn't useful at all.
