Those instances are still on Lemmy 0.18 where the bug got introduced, not a Jerboa problem. Literally all the apps and frontends were affected.
I haven’t noticed that & I check quite a lot. I guess I need to take more time & check more. Anyway, this sounds like a bug. Maybe you should go & report it on Github & let me know when you get back.
Not only on Jerboa. Basically all titles are affected, and it is not only the ampersand which is an issue.
Eternity here, but same thing. I also see a lot of and such
Same for Memmy
