With the cookie regulations (GDPR) in Europe and Google's phase out of 3rd party cookies, do analysis tools like Mixpanel, Google Analytics, Heap etc. still work properly and continue to provide reliable information?
I understand that Google now uses 1st party cookies, and they can do this as they own browser, search engine, and their analytics tool. But how do other analytic tools do this without 3rd party cookies?
And if a number of users in Europe do not consent with using analytic cookies, does the whole analysis not become very unreliable?
