Inconsistent DeviceID Values Affecting Funnel Conversion Analysis

Hi team, I’m seeing inconsistent deviceId values between funnel events for what appears to be the same user. For example:

Event 1: onboardLanding
Event 2: clickCategory
Both events happened within milliseconds, from the same city (Jeonju, South Korea), same browser (Whale), same OS (Android), and same referrer (m.search.naver.com), but the deviceId is different, so Mixpanel treats them as separate users and doesn't connect them in the funnel.

Here’s a screenshot showing the issue 👇 (attach image) How can we fix or prevent this kind of tracking inconsistency? It’s impacting our funnel conversion analysis.
