Recently we made some changes in the system restricting attachment tab. Attachment tab is shown only to assigned group. After that attachments stopped saving. No error occurs during save. just not attached. We found temporary solution. Saving form with any change enables saving for some time. And after some time problem comes back
We declared variable that is calculated in format control and depending on its value (1 or 0) attachment tab is showing.
What can cause this problem and how to solve it?
