Removing support and the capability to play older versions of games is nothing new. At the end of the day, Nordeus is a business and why would they look backwards when they want to improve and update the gameplay especially when older devices cannot handle the algorithms that are constantly evolving.
Because it doesn’t suit you exploiting the old version (nothing wrong with that) you are unhappy because just like everyone else you have to update the game.
Of course, it is your choice whether to move with the times and update or delete it.
Whatever you do, I wish you well.
