The other post[0] has a link with a more balanced take which provides what some of these app store rules are. It's curious that they don't simply add the necessary (by store policy): '"Compatibility updates" include device resolution adds, of which there have been three since the last time the game was updated.'
That is not a change to the game (or their art), simply an update that keeps the game in compliance. However, that would also mean that they now have to comply with the newer privacy policies that have been put in place since their last update, and declare what data it and any 3rd party dependancies siphons from Appstore users. IMO, it's worth considering that that would be worth causing a fuss about if one did not want to expose this information.
