I’ve recently started Data Science path and had no problems with the platform so far.
Today I want to start SQL: Intermediate (LINK) and the Database Schema says “Schema undefined.” all the time. Also, can’t return any queries so I can’t see any results of my codes, makes my learning difficult.
Like I said, had no problems before but now nothing returns on the platform. I tried previous SQL projects as well. What happened? What should I do?
