Delays in analytics events have increased and now reach up to 1 hour and 45 minutes for all customers. Segments that rely on these events may not be up to date while our Engineering team actively processes the backlog. Campaign and flow sending, along with open and click events, remain unaffected. We are working to resolve this as quickly as possible and will share another update shortly.
