We have a problem with pdf attachments for our email notifications. even we click the setting “Attach file to Email notifications” https://prnt.sc/22kewuz
Have attachments ever worked on your installation? Are you using an SMTP plugin? If yes, which one? Are you able to successfully EXPORT pdfs from the plugin’s EXPORT tab?
