I have a weekly automated newsletter and I wish to send out only articles published since the last newsletter (using the Last posts block). But it doesn’t seem to be working that way. Each week, I have to adjust the number of posts to ensure that all new posts are included and old ones excluded; otherwise, it will pull the number of posts specified in “Max Posts” on the Filters tab. On the Advanced tab of the newsletter settings, the information appears correct. It lists the Last sent time correctly and the next run data and it states: “Last time a newsletter has been generated and sent. This date is used to extract new contents on next scheduled run.”
Am I misunderstanding how this is supposed to work or is there a problem?
