stop warning dialog on every save (xls)
Since the 16.x version of Excel 365, I get a warning dialog every time I try to save a file in xls format. Since I am working on dozens of existing spreadsheets, this is a total nightmare because every time I save I get a warning about possible data loss because of the xls format. There is no way to disable the dialog. This did not happen with 15.x versions of Excel. Please add a "do not show anymore" checkbox to that dialog or an option in settings to disable that check.
