Thanks for this thread! It also just helped me figure out a problem with featured images no longer appearing as long as Mailmunch’s landing pages were set to active.
(Just writing this in case someone else ever has the same question and stumbles upon this thread)
Thanks for the super fast reply!
It just looked like too much of a coincidence for this to happen right after an update of Postie, but I’ll take it up with the theme developers instead.
