Microsoft deleted all my work? Microsoft Whiteboard

[silkair]

So basically for school im doing a presentation and i need to access my work but for some reason when i opened up microsoft whiteboard all my work was gone and it said "Optional connected experiences have been turned off by your admin, If you want to turn them off, go to the settings menu." and when i turned it off and refreshed my work was still gone.

Is this like a school thing? because i used it for my other classes but it just stopped working.
If it's not a school thing can someone tell me how to fix it?

Not sure what you did as the sentence is confusing. But you need to talk to the school IT department and the administrator as the message you've got says that the optional connected experiences has been turned off.
