Summary

Conditionally skip ODP identify events when the user context contains only a single identifier. Single-identifier identify events provide no linking value and create unnecessary network calls.

Changes

• Modified identifyUser in DefaultOdpManager to check identifier count before sending
• Filter out empty/null identifier values before counting
• Include stored vuid in identifier count to ensure accurate multi-identifier detection
• Log debug message when skipping identify event
