I have the above issue from Google. Inject metadata was enabled.
The simple option seems to be add header content, so I have done that. The problem is this:
The Canonical at Line 79 is the generic blog page, presumably why multiple duplicates are being flagged?
The Canonical at Line 168 is the one that I have added in Header content within Poster 2. Presumably google will ignore the second one?
Any experts please? It really hurts that Google is currently not listing my content.
