App's aren't working

Posted by Helen Sai


I'm making an ILS and i have a little problem. I wanted to add some apps to my lesson, but when i'm trying to open it, it says: Something went wrong during the startup of the observationTool (or any other app's name) A problem occured while trying to setup access to the storage. "The document storage location is not present."

I really need those app's. What should i do?
