I just wanted to work on the Mastering ROS with the Summit XL course and I come to find that it is not working at all. My co-students find the same. We tried with different browsers. During the day, there were also some issues and after that, we received a message that some issues were fixed and now it is not usable at all. I hope this will be resolved soon.
My apologies for this error, it was a glitch on the front end (not the course). It’s now fixed. Please clear your browser cache and try again.
Thanks for your patience.
