For the past several hours the instructions section of the ROS navigation in 5 days course has not loaded for me. The terminal, IDE and sim are working normally but the instructions keep spinning up. I have tried using different browsers and computers and nothing will fix it.
I apologize for this glitch.
This should not happen, but it could be a temporary problem with the specific VM you were assigned. Could you try again and let us know if it happens, which browsers, including a screenshot?
