Voyager PWA, but I think see what it did now.
It's processing as markdown, and ignoring the first tilde strike marker since it's sandwiched next to the URL brackets. So the only valid strike through is in different spots than you intended. Superscript/subscript I think is being processed correctly because it's small.
Edit: I just noticed the other guy has the same app, so that would do it.
Edit2: I think I need to mentally review how markdown works there are wires crossed in my brain
Heyo, just wanted to say I appreciate the edit.
Some people see three extra clicks (which is what it took on mobile to get the real description out of GitHub) as a limiter. I actually clicked because I had guessed that with a name like "navidrome" it was something GNSS related, was surprised to see it was about music.
I've been self hosting for going on 7-8y, following various communities on reddit and Lemmy and I learn about new softwares every day. I'll have to toss this one on my investigation queue.
