What happens next
Once events start flowing, CrossTrack automatically creates profiles for anonymous visitors.
When a user logs in and you call identify(),
the anonymous session merges into a known profile. Check the Overview to see your events and profiles,
or read the full docs for WebView bridging, cross-domain linking, and more.
