The game behaves in such manner when influenced by an unstable internet connection or server instability.

Since Tennis Clash is an online multiplayer game, it needs not only a strong Wi-Fi signal but also a stable connection. Also, specially after updates and new features are released, many players will try to connect at the same time. This can cause some lagging and disconnections.
When this happens, try to restart the game and/or restart your device to check if the issue gets any better.

Please check out this article to understand how lag affects the game and how you can prevent it!
