Link to mastodon account / posts

Hi,

I have a mastodon account on mas.to, which is one of beehaw's linked instances. When I search for my username on beehaw (@madeingermany@mas.to) or the profile link I don't find anything.

It does work the other way round :) https://mas.to/@marco@beehaw.org/

Should this work, or am I misunderstanding something? Thank you!
