This question already has an answer here:
I've been playing the game for about a week without issue, but all of a sudden today it stopped earning credits while I am away from the game. My stores are stocked, the game is properly counting down time (projects are getting completed), but the only time the game earns credits/has sales is while I'm actively playing it.
Is anyone else having this issue?
Note: I have the game for Android, and there might have been an update today
