I have a new microsoft form, have tested with it saved as both a personal form with a business account and as a group form. The form has saved perfectly until the last question.
If I add the file upload question the page status will move to saving, but will never move to saved. I have tried refreshing and the question is always removed when the page reloads. I have tried updating other questions and all changes are saved correctly. Settings are set so that only people within my organization can respond.
