Day limit of classes

There is some daily limit of classes, because it is loading and does not let me continue, restarted several times and nothing when I want to continue with the next class does not load

no limit - can you give more infos on what’s happening? on what page are you? what are you doing? what’s happening? what should happen?

I’m in css I started today with html and now I’m in the middle of css course and the class doesn’t load, only the loading icon appears.
Ok its done i change brownser and now its ok.
