@gotosocial oh okay, @takahe we tried to tag you in the original post, but apparently there's federation issues between Takahe and GoToSocial.
Hopefully we can fix this soon.
@maloki Initial federation investigation reveals it's our problem and (surprise surprise) it's JSON-LD - our parser doesn't like the way GTS includes the Mastodon namespace (https://github.com/jointakahe/takahe/issues/223). We'll try to figure out how to make it happier!
