So, I have the main static page on one server *(e.g. `example.com`)* and a single page application *(Angular)* on another server but on the same domain with a subdomain (e.g. ma app here - `sub.example.com`). In the static page *`(example.com)`* I've installed GA and GTM, and on the application initialized GA and GTM once again when the user navigates to it *`(sub.example.com)`*

Also, I have run ad campaigns on facebook and google. 

I need to track the users that came from ad and navigated through `example.com` -> `sub.example.com/registration` -> `sub.example.com/user` - it will be a goal (or sort of conversion goal).

If it real, how I can track it?



**UPD:** I've fixed tracking goals by replacing `analytics.js` tracker to `gtag.js` and rewrite my tracking system according to the gtag requirements. Not sure, but hope that now I can track users from ad campaign to destination.
