    Appium may have limited support for older versions of iOS and Android, which can be a problem for testing applications that need to support a wide range of devices.
  • Lack of Advanced Gesture Support
    While Appium supports basic gestures, handling complex multi-touch actions and advanced gestures can be cumbersome and sometimes unsupported.
  • Flakiness of Tests
    Automated tests using Appium can sometimes be flaky, meaning they may pass or fail inconsistently due to various external factors like network speed, timing issues, and device state.
  • Limited Support for Web Components
    Testing mobile web applications via Appium can be challenging due to limited and sometimes unstable support for web components.
