Zoom meeting ID not valid in notification email

[RobCressy]

I am running into a strange issue that I can't seem to solve.

I am using Calendly for my scheduling and have Zoom integrated. When someone books a call with me now, they are receiving a "Your Meeting is in 1 hour!" email, and it sends them an automated message saying "Your appointment is now" and then it includes a Zoom link that is invalid (it's the same link every time for everyone). 

I've reached out to Calendly support and this isn't on their end. I don't even have a notification set up for someone to get an email after an hour. So I have no idea how this is happening, but it's causing a major issue because people can't log in to my calls because they are attempting to click a zoom link in their email that isn't valid. 

Can anyone help?

hi @RobCressy ,

Yes, I have had this happen to me with calendly in the past.
I think I deleted the zoom connection and then reconnected.

But I may have deleted the appointment type too, maybe overkill
I am pretty sure it is calandly being lazy and not checking for failures when connecting to Zoom.
all the best
