Didn't think so.
After a year, the CCC interface on Chrome is still broken

So if chess.com has a million payments of fifteen dollars, which is certainly possible... then where are they spending that money? Why are they charging it to begin with?
The video section is dead too.
There are the main sections and then everything else is just dead weight. You're focusing on puzzles. Good. Maybe focus on every aspect, since you have the money.
This site is clearly designed to go up someone's nose.

For a bit more context, apparently chess.com made $157 million last year and employees 727 people. Think about those numbers. All they sell is access to a website that already exists. So what are those 727 people doing, if the site never changes, and where is that one hundred and fifty million dollars going, if not up someone's nose?
This is why you really should have listened a year ago. If you're curious why no one is going there, that's partly it. Partly that, and partly that no one over there seems to be familiar with engine tests. But nonetheless -- even if you're not going to bother to put the version number in your PGNs, which is ridiculous -- even then you should at least have a working interface. This is part of what people pay for, or is that more of a throwaway section? You could really do a lot with it.
