I might be misremembering, but the previous official statements from Meta on Threads integration was that it would start as a one-way push. Meaning that Mastodon clients could follow a Threads user and see the discussion happening on Threads, but that it would NOT merge back any comments Mastodon users would post.
Did they announce the two-way sync should be operational by today?
@airwhale Nope, and that isn't the issue. The issue is they hid a comment that simply mentioned "Pixelfed"
