Hi everyone , I usually notice we used to get pageview call with the method GET but here in my website we are getting POST method .
Also one more iisssue , in some pages we are getting 2 pageview call one with POST and other one with GET .
Can anyone please explain me , what it is exactly, how this can be resolved ? Which one we are supposed to get and will they reflect in analytics?
