What list of things would one suggest that I do if my students are not receiving reminders for upcoming assignments on Microsoft Classroom?

1. Check the Settings: Make sure reminders are turned on in Settings or in the assignment details.
2. Check the Parent/Guardian Connections: Make sure your students have established a Parent/Guardian connection.
3. Check for Student Assignments Filters: Ensure any applicable filters aren’t excluding the assignment from view.
4. Check for Classroom App issues: If students are experiencing issues with the Classroom application itself, reinstall the app.
5. Validate Classroom Permissions: Have students validate their Classroom permissions.
6. Check for Account Issues: Have students check their Office 365 accounts for any issues.
