Event Deduplication has stopped being reported

For anyone troubleshooting their GTM server setup and testing browser and server events reporting on Meta, it’s possible that Meta’s ‘Test events’ tool currently isn’t indicating whether deduplication for any event is being performed.

However in ‘Overview’ mode, I can see that both browser and server are in sync with the numbers reported for events.

However, when reviewing the details, I see the following:
Page View: Event Deduplication Meeting best practices.
Lead: Event Deduplication Not meeting best practices

Thus the Lead Event is showing agreement in browser and server events but not being deduplicated.

Has anyone experienced similar?

Meta interfaces are often glitchy and may display incorrect information. At the same time you should make sure that your web event and its server copy have the same event id parameter. If they are the same, deduplication will work without problems.

Thank you! I figured after multiple testings.
