Not sure how you’d go about fixing this. But in the comment https://sopuli.xyz/comment/19414295 is a link to https://www.youtube.com/c/Partizánmédia/streams that Summit tries to open as a community. Maybe you can continue on to the normal Android link handling if no Lemmy or Piefed API can be found on the server.
Tesseract used to have that same bug. To fix it, I now poll /api/v3/federated_instances at startup and save those to a lookup variable. Before localizing a community, user, post, or comment link, it checks to see if the domain is to a known federated instance by looking for it in the list of federated instances.
There may be other ways to solve that problem, but that was what I went with. Bonus is it doesn’t require any extra network calls beyond the one to fetch the list of federated instances at startup.
