The following information is wrong: "In the Moodle documentation it indicates that it would behave like the previous version 3.9". Where di you see that in the Moodle documentation?

If you want changes to show up in in-progress quiz attempts, you need to regrade them.

If it has not already been said, the other thing that really helps is to have lots and lots of RAM, and tune the database engine to use the right amount for caches etc. Just follow standard DB tuning guidance.

And, with any of these things, if you can set up a reasonable realistic load-test, and then for anything you might change, you can compare before and after performance, and be sure you are moving in the right direction.

There is still work in progress.

That work does not really alter what you talk about.

I agree it would be nice to make this better. The thing I notice is the number of people who have to come here to ask, to find that Add -> A random question is what they need.

Not sure another tracker is particularly helpful, until we have some idea what should be done. (I don't know if there is one yet.)

The quiz reports list all the attempts, with the current state - not sure how easy it is to get the count from there.

At the moment, on the front page of the quiz, there is a summary like Attempts: 123 (as a link to the reports). Would it be nice to make that give more informative, like

Attempts: 123 (45 in progress, 78 finished)

(The code for that is in quiz_num_attempt_summary() in mod/quiz/lib.php, if you want to try changing it.)

If you are not seeing a warning, are there any errors in the browser developer console?

(Acutally, if you have Debugging set to developer level, I think quiz auto-save puts some messages about what it is doing in the Console.)
