I get an error when I try to add a participant

If you get a prompt like "5 users were added successfully. 3 errors was detected. Fix them and resubmit", it could be due to one of the following reasons:

• A user has blocked Remind by texting STOP. The user can re-join or resubscribe by texting the class or school code to the Remind number, 81010. 

• A user has been banned from the school organization.

• A user has been blocked by the owner of the class.

• Users under the age of 13 aren't allowed to join a class that is owned by another student or parent. 

• Users under the age of 13 aren't allowed to join a class that hasn't been linked to a school.
