We’ve implemented Snowplow JS tracker (v. 2.18.2) via Google Tag Manager and we suspect that it doesn’t deduplicate
The single tracker (and so the collector url) is used across multiple websites.
Instead of generating a single
domain_sessionid in the activity session, we’re seeing multiple
domain_sessionid, sometimes even for each page viewed within the session.
Mostly iOS users are impacted by this.
What could be the reason for this? Is it possible that we’re blocked by some browser with writing into the local storage? Especially if the collector URL is from a different context than the client website?
