Yes, they're changing and will stick until I either hit save settings in the main settings area or restart the app. Seems like other settings aren't saving either, like default sorting.

Theme colours are still unfortunately not wanting to stick. If I change the colours and tap save settings, then back out to the main settings menu and tap save settings there the colours immediately get reset to default.

Regardless of being stuck on the not so nice default colours, this is definitely the best Lemmy app of all the ones I've tried and solidly in the daily driver spot. It doesn't feel like an app that's only been in development a few weeks.
