@hum I'd be happy to help with any questions you have, but I will need additional information to do so.
Can you explain your issue a bit further? The more details you're able to provide, the better equipped I'll be to help.
I look forward to hearing back.
Thanks for following up, @hum.
It sounds like you might be running into network firewalls at school. Sometimes IT departments decide to limit their user's access to music streaming services like Pandora. If it isn't working on your school issued Chromebook, you may want to check with your IT department to make sure that they haven't blocked your access to streaming services.
Let me know how it goes.
