We are running into an issue where we have built a custom powerapp that will replace placeholder values with inventory data. If a user deletes a placeholder value after and saves the user can then see the old placeholder values in the powerapp. This can be confusing to the user since it is deleted in the email body and preview however for some reason the placeholder values are not updated. I was told that this was by design and the placeholders are not updated until the ready to send button is pressed. It would be nice if we could use JS/power automate to call the validation step manually, so a dev could call that on a button click or if the user was given an option to refresh that placeholder data so this would stop the placeholders from holding deleted values until the ready to send button is pressed.
