Hi West Patent,
You should have received a call or message from the District acknowledging a problem with Launchpad this morning. You can try restarting your Chromebooks. You can also bypass Launchpad to access Google Classrooms directly:
Go to classroom.google.com
Student login with email first firstname.lastname@example.org eg Jane Smith is JSmith@student.bcsdny.org, then
password is usually "wpes" plus their student id, eg wpes12345
Good Luck, and remember today is a Half Day!
