Hey @Stratelier,
We do recommend when not playing, especially for extended periods or over resets to force close your game.
In the meantime, I have shared these examples with the team as there were some changes put in place a while ago to prevent issues with game sessions being left idle in the background.
But you mentioned the game crashing when returning.
- Does this crash to the Nintendo home screen or just restart the game?
- Was there any errors before this?
