Hello ricsdpl I don't think you can make any edits once the personal link is generated.

Aanurag_QC is it possible the previous personal link that generate still work after a change?

As far as I know unless and until the links are not opened, one can make changes to the embedded data, as the embedded data are stored once the survey is completed.

Aanurag_QC Some of the personal links are already answered however there's one email address that is need for a correction/change and that not yet open and answer. Is that possible to make a change? And how can I do it?

ricsdpl I did a quick test that involved the following steps
1) Generate Personal Link
2) change the email address in the contact directory
3) Open the survey link and complete the survey
Result: the latest changes were considered to be recorded in the response.

So in a nutshell you should be good to make the change as long as the survey is not completed.

Aanurag_QC Thank you!
