Issue with _driver.Notificationbar; (Android)

I’m having an issue with objects on _driver.Notificationbar;
when there are many objects , so the CLEAR button is hidden, the objects(notifications) count is 0.
var findelement = _driver.FindElements(By.Id("android:id/text"));
but when the CLEAR button is visible, the count is according to the number of objects on screen.

it used to work good, but something went wrong.
any suggestions?
Thanks
