@aleksey@shpakovsky.ru the basic support for receiving/processing update is already there, what's missing is sending update (and have the UI to support it).
I do see the updated version here, I think the update was only sent to the mentioned people/followers, if you received the object via an announce/share, that may explain why you haven't received it.
I would need to check how Mastodon/other implementations handle that.
