Security Settings

I continue to have issues with Zoom's security settings that cause customers to miss meetings. Just today, for example, I had a sales call and my customer was stuck in the waiting room and I didn't receive a notification. 

How do I disable all security options? Zoom is forcing me to choose one. I'd rather not have to secure my meetings. There's nothing sensitive being discussed. I just want to make it as easy for people to join as possible. 

If I can't figure this out I'm switching back to Google.
