We often send emails from Outlook to Monday items. Everything comes through to Monday Updates OK - including attachments.
However, when sending emails from Gmail, only the email comes through - no attachments.
Monday support say that this is a known issue and they are working on it with Gmail.
Request that attachments from Gmail come through to Monday Updates - same as they do from Outlook.
P.S. It would be handy for this limitation with Gmail to be mentioned in the Monday support article.
