Is there a way to allow multiple submissions of a form

I have a few forms that need to be enabled to resubmit with minor adjustments after being completed by a customer, how would I make this possible? They are receiving an error message that does not allow them to complete the form a second time

Forms by default accept multiple submissions with no limit. Unique Submissions is probably enabled in your form that's why users are unable to submit multiple times.

To lift the limit, set Unique Submission to NO CHECK as mentioned in the guide.
