My assumption was that the product teams were supposed to be checking here regularly.
That depends on what your definition of “regularly” is.
I’m on a NOC team I check our whole communications platform every half an hour if I haven’t seen any notifications pop up on my screen, but that’s a realtime monitoring cadence … product management should have a daily expectation to get caught up. They should distribute/adjust the filtered info as needed for their teams to succeed in fulfilling the client needs. Not everything needs to jumped on in this situation obviously… but barring my reasonable expectation for consumption, communicating that the message was received at all would be 100% better than the current state.
