I have my default sort set to "Hot" inside lemmy.world. When I open Jerboa, it shows posts from my subscribed communities sorted by "Hot", like it's supposed to. However, whenever I open a community, it show the posts sorted by "Active", and I have to switch to "Hot". This is different from the main web site, which uses my default sort when opening a community. Changing the sort inside the app doesn't change anything - the next time I open any community, it's sorted by "Active".
It would be nice if Jerboa was fixed this so communities were sorted by my default sort by default. I've made (simple) Android apps before, so I can try looking into it. But mostly I don't know the appropriate way to add an issue so it gets tracked and fixed eventually.
