Why survey question answers aren't saved instantly during user input (but used to work)?

[lidorz]

Hi,
I'm working with a public survey and noticed something strange.

A few days ago, when a user typed into a text field (e.g., First Name), the answer was saved instantly to the asmt_assessment_instance_question table in "string value" field — without pressing "Next" or "Submit".
This was perfect for field validators and logic based on live input.

Now, it only saves when the user clicks "Next" to go to the next category.

pagination setting is currently set to "One category per page".

Any official guidance on what triggers answer saving during survey input?

Thanks!

What happened between then and now? That would help in troubleshooting from our side.

Did you have any upgrades (version/patches) or any plugins updated?
