Are you getting an error message like this?
If you are clicking to join from the email sent out by IPS, something to keep in mind is you need to sign out of your personal Gmail account before logging in to use an IPS's Google Account. Or if you are on an Android/iOS device you may need to add your child's IPS Google Account to the device.
Your child's IPS Google Account has already been added to the correct Google Classroom, so you only have to log in to access your child's Google Classroom. There is no need to join by code.
This error is happening because you are signed in to your personal Gmail/Google account. When you must be signed in with your child's IPS Google Account.
If you are on a mobile device such as a tablet or phone you will have to add another Google Account to the device. Please see the screenshot below for visual instructions.
1. Tap/click your profile photo (top right corner)
2. Tap/Click Add another Google Account
3. Login using your child's IPS Google Account details.
