Even after this update (6.4.3), gems are still not working... Besides, the unlimited instant mission does not work. We are still needing gems and unlimited instant mission. We kindly ask you to address these ongoing issues as soon as possible, as they significantly affect the gameplay experience. Many players, including myself, rely on these features, and it is frustrating to see no resolution even after multiple updates. Please let us know when a fix can be expected or provide compensation in the meantime. Thank you for your attention and support!
