I worked around this by opening beehaw in another tab and searching for the community/user/post i wanted to interact with. Copying the whole handle (as in your example) into the lemmy.ml’s seachbar showed the desired content on lemmy.ml’s instance.
Another workaround I’m using is abusing the ‘These posts might be related’ query to seach for keywords :D That’s how I found this post; I wanted to create a new one called ‘lemmy and fediverse instances’.
I am trying to interact with posts on beehaw.org on lemmy.ml, but to no avail. Does anyone know how to communicate inscance agnostic?
If you are like me and hear of FSi the first time here: There is a F-Si PeerTube instance (yes this is part of the fediverse!) were one will find all the talks from FSiC2019 and FSiC2022 ready for the looksy:
