I have a form that can't be edited after submission and there are users who write in a support ticket to ask to amend the details submitted.
3 possible choices as I can think of are;
Just a line above the submit button that tells users to check the details and it can't be edited after it's submitted.
Checkbox labeled with "I confirm I submitting the correct information and I can't edit them later on".
Popup that asks "Confirm submission? You can't edit the details after submit it".
What's your thoughts about each one other and possible alternatives to them?
