These problems could simply arise from the fact that Mastodon is starting to really work on the management of Activitypub groups.
And re-invent the wheel once more, preferably in a proprietary way that’s as incompatible with the rest of the Fediverse as possible but sold to the Mastodon users as the Fediverse gold standard.
It is therefore appropriate to report any incompatibilities to the Mastodon staff, so that they can claim the other side is broken unless the other side has rock-solid proof that it’s actually Mastodon that’s doing it wrong.
FTFY

from what i can tell (from the work in progress pull request) mastodons group implementation explicitly does not aim for compatibility with lemmy
other than that, i agree on activitypub being crap in terms of making interoperability easy

@ShittyKopper rightly mastodon cannot and should not aim for full compatibility with Lemmy and Piefed.
In fact, Lemmy has some unique features (such as the intentionally limited management of crossposting) that cannot be managed.
However, it would be appropriate and above all ethical, for Mastodon groups to be compatible with Friendica groups, Gup groups and Mbin magazines.
This would allow mastodon users to continue using the Activity pub groups of other platforms, including Lemmy.
I remember in fact that even WordPress (which at the moment, represents the most important novelty of the Fediverse) is perfectly able to publish on the Lemmy communities and on the Friendica groups!

iirc mastodon was implementing smithereen’s flavor of groups. no idea if they ended up changing course or anything (not following masto dev tok closely) but the way they work is fundamentally different from how Lemmy and compatible groups work
