I can follow and see content from both accounts via the Ice Cubes app.

EDIT: I just realized you can’t see the posts in your timeline. I can only see as far as 2 days ago via my app, so unless you’re able to post an image more recent I can’t help out. Sorry!

Going to mastodon.social and searching for 5teverin0@pxlmo.com in the search field, I see posts going back to August 21 just fine from there. So it's not clear to me what is not working?

Federation of post is not retroactive - if you search up yourself from another instance you should find your profile, but you might not see your old posts. If you follow yourself, all future posts will be federated.

I follow my own Pixelfed account on Mastodon and will often boost posts. I have a pixelfed.social account though. It's probably a federation issue on your specific Pixelfed instance. I've moved the Mastodon account a bunch and I've had problems on specific instances. I was never able to see my Pixelfed posts from fedia.social (ice shrimp), for example.

I was also able to search, follow, and see your Pixelfed posts from mastodon.social.

Edit: Your two newest photos from Aug 31st aren't actually showing up on m.s. and I can't see them on pixelfed.social either.

I can see it from the three medium/small instances I just tried.

Also, is typigraphy a typo (typi?) or its own thing?

The syncing of different mastodon instances is horrendous. I had to leave mastodon for bluesky because of this.

Though I still have a pixelfed account.

OK, I think I have this straightened out. The situation was that only my first couple of PixelFed posts showed up in my Mastodon timeline, anything more recent did not. Somewhere along the way, I unfollowed and refollowed my Pixelfed account, to no effect. Today, I went into my Mastodon settings and saw that my Pixelfed follow was "Pending". I canceled it and followed my Pixelfed account again, and all is well.
