How do I remove SMS templates for appointment communications?

To remove an SMS template:

1. Go to Settings -> Scheduling -> Appointment Communication:

 2. Click on the three dots at the end of a row containing an SMS trigger and select Edit:

3. Click Manage Templates:

4. Click the trash can icon alongside the template you'd like to delete:

5. The template will be deleted, you'll no longer see it on the list and it will no longer be available within the Message template dropdown when creating a communication trigger. 

Note: You'll not be able to delete a template if it's currently used in a communication trigger.  You'll need to change the template used in the trigger first.
