There's an awful lot happenening in Teams, so how do you know when new stuff is there for you?
Notifications are really helpful, but they can be irritating. You want Teams to tell you when there is an important message for you, but you don't want to be disturbed in the middle of a meeting with your teacher or while you are getting on with your work, and you dont' want to get lots of messages that don't apply to you.
You can customise your notifications settings on your device so that you only see the important stuff, and YOU can decide whether you want it to go ping or not!
It's quite complex, but hopefully this video guide will help you. You might need to experiment with different settings until you find what works for you.
