Event properties showing as over quota for orgs using Guides and Surveys
Started: Apr 13, 3:45 PM
monitoring
Erroneous events have been deleted. Event property limits should be accurate again and new event properties should be usable again. Any event properties that came in only during the overage window (and haven't been sent again since) will not be usable until post-processing occurs at end of day.
Apr 13, 8:53 PM
identified
At 8:45 am PDT, Guides and Surveys added a large number of event properties.
Which projects are impacted? Any project that previously had less than 2000 event properties and that now has 2000 or more event properties.
What's the impact? All such projects are unable to (a) add new event properties and (b) use those new event properties for filtering, creating cohorts.
The issue has been identified, and the team is working on a fix that will remove all of these event properties. You may see...
