having to log in again every time I make an appointment through zoom.

Every time I now make an appointment through the zoom application on my computer, it bumps me OUT of my calendar and I have to sign in again.This NEVER used to happen,but it does now. I don't know how to fix it nor who to talk to to fix it. As I use Zoom most days during business hours to conduct my business, this is time consuming. I need help.
