I will concur with this one. When I created an automated sms for this purpose, the link I put in doesn't work.

You could always set up a webpage on your personal website with a message that essentially asks for this and then have a link on the page that takes them to the review page. Then, just set it on the form to direct to that page after the form is submitted by going to the form settings and adding the link to your website under the heading of 'When form is submitted, redirect client to:'...just a thought.

So much this!!!

yes

What about the "scheduled" message type in the automated email? Would that not work - where you select how many days (not necessarily # of visits) but you could set it to go out in an estimated amount of days after a certain appointment.
