A web-based tool in Microsoft 365 that enables users to quickly create surveys, quizzes, polls, and feedback forms.
Dear Louis Phelps,
Thank you for posting back and sharing with me the detailed information.
It seems that this date not update issue only occurs in a specific Microsoft Form.
For this specific Form, you may try collecting response by using link Only people in your organization can respond and require users sign in to access the form.
If same issue still happens, I understand how frustrating this situation can be and sincerely apologize for the inconvenience caused.
I'm afraid the problem is related to the backend and it's better to further check the Form from backend by the related team. So, I suggest you raise a support ticket from the Office 365 admin center, where the related team will collect the background logs and find out the cause of the problem. This would be the most efficient way in handling this case for you.

Note: To create a support ticket, you need to have Microsoft 365 admin privileges.
Apologies for redirecting you to the related team support as the moderators in this community have limited resources to check the backend information, and to get the fast and better assistance we requested for it.
Appreciate your patience and understanding. Have a great day!!
Sincerely,
Tina | Microsoft Community Moderator
