Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?

React since 15.6.0 and up (15.5.4 works fine), iPhone 6s (IOS 10.3.2), Appium 1.6.5

Hey, @ikhilko! Thanks for the issue. Appium is probably setting the value by setting the value property on the input element. This won't work with React's controlled input implementation. I would recommend referring to Appium's documentation to see if there's a way to ensure actual keyboard events are being dispatched, or opening an issue in their issue tracker if not.

Hi, @aweary! Thanks for your response. Appium (and Selenium itself) use more complex logic to input value to the inputs. I will try investigate what they execute at that case. But it's very strange that that logic works fine on Android (Chrome), but doesn't work at IOS using React. Can you refer some information about how React works with controlled inputs? It will be very helpful in my research of this problem.

Looks like the same reason as issues #10135 and cypress-io/cypress#536
