If you're an owner or admin you can change the notifications settings of any of your staff members at any time.
To do this head to Dashboard >> Staff >> Options >> Edit Notifications Settings
From here you can decide which notifications you'd like your staff member to receive (including TeamUp updates), by simply toggling on/off the available activity alerts.
Note. the options available are based on the staff account permissions, so, for example, a staff member who only has access to classes can only get notifications related to classes and not those related to customers.
Once done your staff member will start or stop receiving the relevant notifications chosen.
