2020 October UPDATE: With the release of Google Analytics 4 (App+Web/Firebase), the old tracking code (analytics.js) is no longer supported, only GA4 and gtag.js are supported going forward.
2019 September UPDATE: In September of 2018, Apple rolled out its Intelligent Tracking Protection (ITP) 2.0 program. When ITP is activated, third-party cookies can only track a user’s activity across sites for 24 hours from the exact moment a user visits a website. After this 24-hour window, these third-party cookies are only able to “remember” a user’s login information. With ITP, all third-party cookies are gone after thirty days.[link]

Use Google Analytics tracking via GTM in order to avoid any code conflict and use a conversion linker

Of course, this is done with Google Analytics and Google Tag Manager, which, ironically, are also the target of adblocking plugins – but we’ll get into that later.
