1. The developer may have stopped developing and updating the game, which may be due to insufficient game revenue, resignation of team members or other reasons.
2. Developers may be updating and improving the game, but it will take longer to complete. In the process of game development, sometimes it is necessary to solve some technical problems, or it may take a long time to test and fix errors.
3. The policies of game platforms (such as App Store and Google Play) may have changed, or the platform has found some problems that do not meet its requirements, resulting in the game being taken off the shelf or needing to be modified before it can be put back on the shelf.
Whatever the reason, if you want to know more about the game update, you'd better consult the game developer or publisher directly. They can provide more specific information and answer your questions about game updates.
