You can now restrict the booking of specific Appointment Services by tag.

In other words, if you've tagged a special group of customers, and want to ensure only this group can book this appointment service, you can now restrict booking to just those individuals.

To do this, click Appointments > Services > locate the service > click the dropdown menu to the right > click Edit

Next, scroll to 'Who can book?' > toggle on 'Restrict booking to customers with specific tags' > choose which tags just below (use the dropdown carrot to the right to show existing tags).
