I am finding that updating the content of an email, specifically a Content Builder email, that is set as the email in a Triggered Send DOES NOT update the content of the email sent by the Triggered Send. It just sends the previous 'version' of the email with content as it was when originally added to the Triggered Send.
I have tried pausing then resuming the Triggered Send hoping that would trigger the send to update the email to no avail. I have also tried search help and documentation to no avail, though I did find instructions on how to update it should it be part of a Journey -- mine is NOT part of a Journey, its a stand alone email send.
Is there a method to update the email content within a Triggered Send, preferably via Api, that will update the email sent by the Triggered Send to match the updated email content?
