Actual Behavior

Was working through Missions. After importing world-database.zip I decided to remove most of the tables inb my testing app, “Test1” and re-im port the zip file. Now all screens show the " Opps! Something went wrong. [Report a problem]".

I logged out, logged back in, created a second app (Test 2) but this, and the original app, have the same problem.

It looks like something in my profile has been corrupted.

Loggin out, closing browser tab, new tabd and logging back in solved it!
