We do not want guests to be able to cancel their appointment via the confirmation email. If clients wish to cancel, they will need to call. This allows us the chance to get them rescheduled rather than just canceling their appointment. We won't be able to use the email feature at all until this is resolved or it's going to impact us in a very negative way. I saw at least 5 other posts for the same idea so I think if you merge them all you will see there is quite a need for this. This seems like a pretty straight forward feature that is offered at Meevo2, Booker, as well as many other booking platforms so it should be quite easy to implement if you want to help deter cancelations for your accounts, which is in all of our best interests.
