Some respondents told me that when they are filling the survey, the can see some question's answer on the screen. I don't know why. But I think that why some responses are not saved.
Would you please double-check it for us? And let us know what we should do to avoid it?
Set "Allow multiple responses or update responses with one token" to NO can avoid it? Is it necessary to set "response token persistence" to YES (Maybe NO) at the same time?
One more question: If respondent can update his/her response with token? What do used to retrieve his/her answer? IP or token or something else?
Many many thanks!

Yes, think so.
You can test yourself with 2 browser .....
2 different $_SESSION , same token (one time ) : each time a user "submit" a page (click next/previus or save) the DB is updated to his $_SESSION.
PS: same IP or not : it's the same. It's $_SESSION only and token only. Different IP : same than same IP.

One token with answer persistence to YES can do this if 2 user open a survey with same token.
