This feature gives you control over the amount of lead time between when participants can book a session and the session itself. So, for example, setting the minimum scheduling notice to 4 hours will let participants book themselves for a session up to 4 hours before the scheduled session time.
The minimum is set to four hours by default. However, you can change this buffer to suit your needs. Keep in mind that all active projects will adopt your changes in real time.
To edit your scheduling notice, log into your researcher account. Click your name in the top navigation menu. Then, click "Edit Account".
Scroll down to "Calendar rules" and enter the number of hours you need to close off participant scheduling before a session.
Don't forget to save your changes!
