Yes! To avoid sessions running automatically during Thanksgiving/Winter/Spring break, all teacher sessions can be turned off under the Teacher Product Settings in Org Management: https://manage.goguardian.com/products/teacher/settings
This is a popular option during breaks or holidays for schools, particularly when students take home devices. This prevents any teacher session from running automatically and prevents students from being automatically restricted in a Teacher's Scene. Please note, this also means no sessions can be manually started. This setting is not recommended if some students might be in summer school or weekend sessions.
Can I turn off only automatic scheduled sessions but keep manually started sessions? Not at this time, but this is a feature that we know some users are requesting! If you would like this feature, please upvote it along with others here.
