We just released version 2.6.0 of the #ActivityPub plugin for #WordPress

@[email protected] Okay, so I've tried debugging this a bit and I'm at a loss as to why the notifications don't show up on Mastodon.

I can confirm that:

The mention is an anchor in content
It has a corresponding entry in tag
Each mention in tag is of type Mention with the user's ID (not url!!) as href, and name is their full handle with @ prefix and domain.

Not entirely sure when it stopped working either, and notifications also do not appear on ActivityPub Academy (running v4.1.18).
