On Responsive 365 forms, I can disable the attachment controls using a rule, but users are still able to delete the attached file if they open the form in edit mode - even though the control is supposed to be disabled. It only seems that adding new attachments is disabled. Deleting the current ones is NOT disabled. Is there any way of disabling the deletion function, too. I would still like the attachements to be openable, though.
There may be a way of doing this through the HTML link control - but I have several attachment controls, all of which I want to make read-only after they are disabled.
How can this be done in 365 Responsive Forms?
