hey , its been a while I have not logged in appium discussion.
Yes, I am not facing this any more in my framework.
Reason I found : script was trying to access a mobile element before the screen / element navigation is completed which was staying on top of the other element.
I have used proper waits in such a way that script will wait till the other section of the screen is moved. Also I am catching the exception and use it inside a condition like if(e.getMessage().contains("Failed to find scrollable visible ")) in my click action utility and calling the click action again inside the if() block.
thanks and regards,
adarsh
