A. To reduce the frequency of ads, consider playing the game in airplane mode. This will prevent the game from connecting to the internet and displaying ads. However, be aware that some features may be limited without an internet connection.

B. If you prefer not to play in airplane mode, you can try clearing the app's cache. Go to your device's Settings > Apps > Plants vs. Zombies > Storage > Clear Cache. This may help improve performance and reduce ad frequency.
