A couple things I'd try.
- Upgrade to Appium 1.6.4-beta so you are on the latest
- Make sure you are waiting long enough for it to become visible
What client libraries are you using? For java, try something simple like this...
WebDriverWait wait = new WebDriverWait(driver, 30);
WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(MobileBy.AccessibilityId("Refine")));
element.click();
