Hello @wingtsundummy!
After the most recent update the pass through redirection was actually working, but I’m not happy with the way it works so I’ve removed it. (I wanted to redirect a whole post to a guest post I’d written another blog. The pass through redirect takes me to the text of the post on the other blog, but doesn’t load the photos. The URL shows as my blog, but the content of the blog to which I have redirected is showing, so there’s no way for the reader to easily navigate back to MY blog – so YES it works, but NO it doesn’t work how I wanted it to.)
I haven’t tried to change a permalink since the update, so I’m not sure if that’s working now. The permalink I DID change before the update (this action alerted me to the problem) didn’t work at all, so I changed it back to the original permalink. Now the original redirection (from blogger blog to word press blog) doesn’t work even though I’ve deleted it and redirected again.
I have no alternative but to try the different plug in that @franktredici suggested and @azn137 tested out.
