Dear WeeblesQ,
Good day!!
Apologies for the inconvenience caused and please don’t worry, let’s work together and try to move in the resolving direction.
Generally, when the responses submitted by the responders in the cloud form are synced automatically to the Excel workbook but since you mentioned the responses Excel workbook in the OneDrive in not showing the recent responses in the Form, I would like to confirm whether you have made any changes to the responses Excel workbook in the OneDrive.
If not and you are occurring the problem, please try to sync the responses to a new workbook and see whether the new responses submitted to the Form are showing in the new responses Excel workbook in OneDrive.
Open the problematic form in the Microsoft Forms> Responses> Click on three dots beside Open in Excel> Sync all responses to a new workbook
If the problem still persists, can you please check whether the problem happens with a specific form or all forms in your Microsoft Forms?
Thanks for your patience and understanding. Have a good day!!
Best Regards,
Sophia
