Why can't I save a computer game to continue it later?

I tried a few things, I searched in the help and with Google, and I didn't find how to save a game against the computer so I can continue it later. Today I started a game, it was going pretty well, but at some point I clicked "help" or something and because of that I could not return to the game. There were zero games in my "current games". I just did the experience again and I confirm this.

Why aren't the computer games saved automatically?

Thanks.

Because those computers were never intended to offer rated games. They were originally developed using java which had to run on players' own computers.  They were limited in function and designed to help beginners learn something about chess.  I can't remember if the java version allowed saving or at least persistence when you went away and came back.

At any rate, support for java was dropped several years ago by browsers and chess.com had to scramble to offer a working alternative.  Interaction with a saving feature was never intended. I am not a programmer, but I imagine that this would have added a lot of complexity. How long the games would be saved, how many, are all questions.

Other questions would exist about saving games when takebacks and hints are allowed. If they somehow did save all those games, the next thing you'd want is ratings, which would be meaningless in such situations.

You think that such changes are trivial but I haven't observed that any changes around here are trivial when thousands of people are using the site at all times.

If you want to play a game and have it saved, try daily chess. All of the rated and unrated games in daily chess against both humans and computers offer a time limit of at least a day per move, though most games go much faster and they are saved, Chess.com has a database of hundreds of millions of saved games.

Chess.com has been working on a major site upgrade for years. They may offer such things in the future but they are having a hard enough time getting the new version to work smoothly for the many thousands of players who come here every day.

Thanks for your answer.

I am not asking for a record of all my games. What I need is only to be able to leave the game and come back later. Being a programmer, I can say that this is not complex to implement. Chess.com has a database that stores the user accounts. They have different fields, e.g. name, email address, board color, etc. They would only need to add a field that would contain a game state as a FEN string (or EPD string -- see https://en.wikipedia.org/wiki/Chess_notation#Notation_systems_for_computers).
