Re: Leave site? - Changes that you made may not be saved - Error message when Submitting form - O365

Update 2 : although I installed the updates, that did not fix this issue. Users were still seeing the warning message. After further research, we determined that the cause of this warning message was that a flow was still running while the user had the form open. After a user saves the form, a flow runs to update the item history. We instructed our users to wait a few minutes after saving a form before going back into the form, and that resolved the issue.
