I have Minecraft Dungeons for Nintendo Switch, and I'm trying to add my second joy-con on Switch for local co-op. The console recognizes both as connected, and other local multiplayer games like Mario Kart work fine, but I can't figure out how to add the 2nd controller to Dungeons:
The screen says "press (something) to join", but no button on the 2nd controller triggers any reaction. From videos on YouTube etc, it looks like usually it says press L/R to join, but there's no indication of what to press on my screen. How do I fix this?
