I’m sorry for the inconvenience, it appears that there’s no simple code snippet for this. The snippet I posted seems to be ok, but if it causes issues mentioned in this topic Booking Confirmation (User) Email issue - #12 by zackgoble4 then I recommend removing it, because we can’t debug issues caused by customizations - this is beyond our support scope. If you’re familiar with development basics or have a developer for custom work, I recommend using the suggested snippet as a starting point.
