We are reprocessing some standard events incorrectly marked as invalid.

The issue is resolved, we now are planning to backfill all the invalid events from that time, and will update again when that is complete.

We’ve confirmed the scope of the issue as impacting most users.
We’re preparing a change that will stop the issue going forwards.

As of around 09:30 UTC, some analytics environments started incorrectly flagging events as being invalid.

The team is investigating the cause of the issue and working to resolve it.
