Unfortunately I don't know how in your case as I'm not even on Lemmy, I'm on Kbin.

This is a prime example of my last point though. Interoperability is all that matters, and we can still communicate even using completely different servers and apps. Just like email. I don't remember there being giant internet flamewars over email clients back in the day, people thought of email as "just email" and it didn't matter what you used.
