We host the newsletter PDF on the club website so that we have an archive and to avoid emailing large attachments out from WebCollect.
To add a new month, go to the Newsletter page in WordPress.
Click on the previous month, click on the three vertical dots to open the drop-down menu, then click "Duplicate"
Rename the top duplicated month.
Expand the new Month and you'll see the previous Month, click on "Replace" and then "Upload".
Alternatively, delete the old embedded file and then type "/file" to see the "File" block. Select taht then "Upload".
