When I save an XLS file with any form control in XLSM or XLSX format and then try to edit this file in office 365 web, the message is displayed and does not allow online editing.

If I edit the file once in the Office desktop app and save it, the file works fine in Office Web.
Do you have any ideia do to solve this issue?
