Crashes for me if I’m on anything earlier than 0.18

I’ve noticed this too. You can work around it by updating your default sort in settings, save settings, and then close the app. when you reopen the app, your sort will be updated. It’s annoying but hopefully will be fixed in 0.37.

Same. If you switch accounts, close the app, and then reopen you’ll be on the changed account. Still can’t change sort though.
