The setting is tied to your instance account, because the backend delivers the results with the specified sorting. If you change it via the browser, it should be reflected in Jerboa.
Ah gotcha - now I see what you meant. Change the settings in the browser and the Jerboa app will respect them.
There's some weird fuckery going on though, as I had set the settings in Jerboa, and that setting showed up in both Jerboa and the browser, but didn't seem to be respected. So in the browser I toggled them to "reassert" them and now it works. 🤷
