cannot find element on iOS

[sagar-patil-mmt]

Element is visible and present on the screen but Appium still can't find it. I tried accessing the element using accessibility id and Xpath but it doesn't work. I am using Appium 1.10.0, Xcode - 10.1, iOS - 12.1.3.
I get following response from Appium

[Xcode]
[JSONWP Proxy] Got response with status 200: {"value":[],"sessionId":"4FC0B498-481B-4599-9A60-B8360E70A9C8","status":0}

I think the issue is because of following reason

My screen reloads constantly(with an interval of 1 sec)
If I reload the screen after 3 sec, It works some time( works when tried finding the element with accessibility id and does not work with xpath).

But Appium Studio finds element even though the screen reloads after every sec and successfully performs the click operation on that element.

Does anybody know how Appium Studio finds the element and Appium inspector couldn't?

Another issue is when the element is found (after changing the reload interval to 3 Sec), I some time get the following error

element.click()] Error response status: 13, UnknownError - An unknown server-side error occurred while processing the command. Selenium error: An unknown server-side error occurred while processing the command. Original error: Error Domain=com.facebook.WebDriverAgent Code=1 "The element '"Accessibility_PrimaryZoneCloseButton" Button' is not visible on the screen and thus is not interactable" UserInfo={NSLocalizedDescription=The element '"Accessibility_PrimaryZoneCloseButton" Button' is not visible on the screen and thus is not interactable}

I added the StaleElementException but it does not throw that exception.
