Update form after submission?

Dear Support-Team,

I have one more question: if a form was succesfully submitted, is it possible for the user to still update it if needed? And is that also possible if the individual link to work on the form got lost?

Thanks for your feedback!

It is possible to let users update their from submissions. Inside of this guide, you can find how to do it:

How to Let Users Update Their Form Submissions at a Later Date

You can also edit submissions:

How to Edit Submissions Made on Your Forms

If you did not provide your user an edit link, you can still create it based on the submissions ID.

Replace {id} with the submission ID and provide the link to your user.

Hope this meet what you are looking for.
