To update the frequency of customer reviews, click Settings > Review Settings.
Scroll to Basic Settings > choose how often to prompt your customers with a review for classes and appointments > then choose whether to only send a review request if someone has been checked in.
This can help prevent a customer from receiving a review request for an appointment or a class that they didn't end up attending.
Next, consider capping review requests to a certain number per day, month, or year.
Don't forget to save changes at the bottom when you're done.
