The signal app does and does the OS once the notification is displayed. The latter is where this issue originates
Apparently if I’m reading the work of others correctly a notification component and subsequent other interaction logs, in this case that the notification was not generated, is also logged in knowledgeC pointing to at least some metadata of non-notified messages logged.
