It seems that for the moment you need to add support to both Google Universal Analytics and Google Analytics V4 because the V4 is not fully implemented (it still does not have the same set of features as the old Universal Analytics).
To add support to the V4 you “just” need to integrate Firebase Analytics and I’ve used this plugin: GitHub - capacitor-community/firebase-analytics: Enable Firebase Analytics for Capacitor Apps</tit
But should I use for Google Universal Analytics? I can’t find anything useful searching the internet. Could you please give me a hand?
