Updates from Amplitude 3
- 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 some irregularities during this time. Once the mistakenly-added event properties are deleted, some post-processing will occur at the end of the day to restore any new event properties which could not be added to event property overages (new ones, added after 8:45 am PDT, assuming the project was put over the 2000 event property limit due to this change).
provider
- 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.
