I am experiencing the same issue. Has this been resolved. I can schedule a meeting on my google calendar, the "add video conferencing" option is available. However, when I try to create appointment slots, the option is not there.

Hello there. 

I'm sorry for the late response and welcome to the Zoom Community.

Just to set your expectations, scheduling should be done on the Zoom web portal(using a browser). You can check out this article regarding the prerequisite and how to set up appointments.

Should you need further assistance, please let us know.
