It’s not working for me. I am using it for a page, not for posts. Does that make a difference?
I see the right number displayed of the merged comments (2324 comments) on both pages.
The comments themselves are not merged however:
One page shows 2323 comments.
The other page shows just one 1 test comment.
I was too fast. It’s not working.
One page with +9000 comments, the translated page has four comments.
Comments aren’t merged.
Yes! It is working with the solution you linked too, great & thanks!
