Hello, while working through the interactive tutorial 1 "Working with app layouts", I made changes to the code, got confused so tried to force the tutorial to reset by reloading the web page. Then when that didn't produce the original 'index' code, I logged out and back in.
At this point I have the sidebar with the tutorial instructions on the left - but the rest of the page is at a completely different state. The "Apps" tab is selected and there is a "Create app" button. And two sample buttons - 'Great Books' and 'Photo Album'.
So what happened to the rest of the interactive interface?
I tried logging out and back in several times and with 2 browsers (Chrome and Firefox) - but still get presented with the above scenario.
Thanks.
