We have set up an anonymous survey and have switched on 'Save and Resume later'. However, when users click the link that was sent to them (containing username and password entered); they open a page Load unfinished survey that displays an error message 'there is no matching saved survey'. we have 250 partially saved reponses in our database that users can no longer update as the link does not work. 
any suggestions? did we forget some key settings to have this feature work? 

LimeSurvey version and build number ?

sorry! 3.22.28 (build 200728)

Can you check the DB yourself ?

Can you do a test of save and see if you reproduce ?

Can you upgrade to last 3LTS version ?

Hi, yes I am able to reproduce. I can access the DB, not sure what I need to check?
I will have to check with our infra guys whether we can upgrade.

If you have a line added with the good name in lime_saved_control table.
 

We are looking into upgrading, in the meantime just wanted to share our findings: incomplete number of responses (via Notifications and Data > view saved not submitted) is 13. export via DB is 21. Export via Notifications and Data tab: export of incomplete responses is 349. overview response summary is full 110, incomplete 348.... I don't understand at all...
