WebDriverWait not working as expected

Solution 1:

Once you wait for the element and moving forward as you are trying to invoke click() method instead of using presence_of_element_located() method you need to use element_to_be_clickable() as follows :

try:
    myElem = WebDriverWait(self.browser, delay).until(EC.element_to_be_clickable((By.XPATH , xpath)))

Update

As per your counter question in the comments here are the details of the three methods :

presence_of_element_located

presence_of_element_located(locator) is defined as follows :

class selenium.webdriver.support.expected_conditions.presence_of_element_located(locator)

Parameter : locator - used to find the element returns the WebElement once it is located

Description : An expectation for checking that an element is present on the DOM of a page. This does not necessarily mean that the element is visible or interactable (i.e. clickable). 

visibility_of_element_located

visibility_of_element_located(locator) is defined as follows :

class selenium.webdriver.support.expected_conditions.visibility_of_element_located(locator)

Parameter : locator -  used to find the element returns the WebElement once it is located and visible

Description : An expectation for checking that an element is present on the DOM of a page and visible. Visibility means that the element is not only displayed but also has a height and width that is greater than 0.

element_to_be_clickable

element_to_be_clickable(locator) is defined as follows :

class selenium.webdriver.support.expected_conditions.element_to_be_clickable(locator)

Parameter : locator - used to find the element returns the WebElement once it is visible, enabled and interactable (i.e. clickable).

Description : An Expectation for checking an element is visible, enabled and interactable such that you can click it.
