Switching user accounts
This only works on mobile devices at the moment - ipads, tablets or phones, but Microsoft are working on making it available in the Windows and Mac computer versions of the app too, so keep an eye out for news!
If you are sharing a divce with other family members who also use Teams (whether that's a brother or sister doing school work or a parent who needs it for their own work meetings) it can be a pain having to log out of one account and then type in your username and password to log in to another account.
If you click on the "hamburger" (the three lines which are usually at the top left or top right of your screen), you should see an option to sign in as another user. Once you've done that, you will see a list of all the users that have signed in, and you can switch between them without needing to type anything in. It's much quicker. If your Year 4 brother is in a registration meeting, and you need to use the same device to go to Year 3 registration straight afterwards, you can just switch from their account to yours. it takes about 10 seconds and doesn't involve any typing!
