We are using Moodle 3.8.
We have seen odd behaviour with the "Clear my choice" button for radio-button single answer quiz questions, when the quiz has various pages and navigation is free.
If a student marks an option A for Question 2 (say), goes to another page, returns to Question 2 and chooses Clear my choice, then goes to another page, then returns to Question 2, option A is marked instead of No choice. It's as if the Clear my choice option is not recorded in the cache of the browser.
Does that make sense?
Has anybody else seen or reported that?
We have seen the same behaviour on Chrome and Firefox.
Any help much appreciated.
