Just a call out for help from fedidevs re: ActivityPub. For some reason that I have yet to discern, my mentions are not reaching end users if they're on a Mastodon instance.

The annoying thing is they used to work, but seem to have broken somewhat recently.

(Thanks @trwnh@mastodon.social (who ironically, will not be notified of this mention) for letting me know about the issue.)

I include each mention in the tag property, and it includes type, href, and name:

• type is Mention


• href is the url of the user (not the ID)


• name is the full handle without the @ prefix

{
  ...
  "tag": [
    {
        "type": "Mention",
        "href": "https://crag.social/users/devnull",
        "name": "devnull@crag.social"
    }
  ]
  ...

The post is successfully federated, and when queried, the mention is clickable and goes to the local account page for that user (as opposed to linking out to the remote page like a regular URL).

Alas, the mention does not generate a notification on the receiving end.

Does this seem familiar to anyone else?
