Q.102 Case: You are testing an Android app using Appium and have encountered a problem where the app is not able to find elements on the screen. What could be the cause of this issue, and how would you resolve it?

A: This issue may be caused by a few things, such as incorrect locator strategies or app context. To resolve this issue, you can try the following steps: Double-check your locator strategies to ensure they are correct and pointing to the correct element. Verify that the app context is correct, as it can affect the visibility of elements. Try to increase the implicit wait time for the appium driver to allow more time for elements to load.
