Using appium 1.7.2, my test ran correctly and never had any issue with clearing text field with element.clear. but now since i upgrade my appium to 1.8.0 element.clear seems to stop working. it didn't throw any errors, it just not doing anything. Besides, my AUT component is using React-Native and the dev just upgrade it and change their library to Redux Form or something like that
Im using ruby, cucumber, XCode 9.2, XCuiTest 2.80, appium 1.8.0, iPhone 7 Simulator with iOS 11.2
