What problems are you seeing?

IDK I can see your post. What parts are broken for you?

In general there are still maybe different issues with federation. For instance lemmy constantly changes there api after software updates. Causes federation issues.
Federation protocol isn’t fully standardized at all! Meaning that all platforms can do whatever they please. Mastodon did lay out the foundation of the standard. But that was mainly about posts and microblogging.

I’m not OP, but I’ve been having issues in regard to consistency when trying to federate microblogs to kbin magazines

I don’t know if this is part of what OP is referring to, but the unofficial FAQ says:

Finally from Mastodon, you can Reply, Like, and Boost /kbin posts. You can also follow /kbin users and subscribe to /kbin magazines.

I admit that Mastodon users can indeed subscribe to /kbin magazines, but it seems useless to do so: even if I subscribe to a magazine from Mastodon, the content added to the magazine will not appear in its feed.
