I am using the Zoom Meetings option on Canvas to manage my office hours. There are two distinct problems I am running into:

1) Some students sign up for a time and are sent an email with the wrong time zone. We are in Central Time and they receive an email giving the time in Pacific Time. I cannot figure out what setting creates this issue. The times are all automatically scheduled in Zoom for me and they do not have this issue. 

2) Some students go to the Appointments page to book a time and see a screen that is the same as what I see. They seem to have permission to edit my Appointments. But this also means that they can't book an appointment just like I would be unable to book an appointment with myself.

Any suggestions would be appreciated.
