Thank you for bringing new powerful additional features to AppSheet. I quickly tested.
I expected that we could be able to access to the attachment files (multiple files) as we see the column name of [Related Gmail Event Attachment];-
My test was to save all the meta data of Gmail to the Google Sheet table where the set of the column names are identical of the virtual Gmail table. I passed the value of this column to the sheet, however, nothing was saved, the column in the sheet side was left null. Could you give us clarify in terms of how this particular column stands for?
