E_NOTIFY_RATE
A notification channel hit its limit
The notifier refused to send because the channel already sent its allowance to this recipient in the current hour; the notification waits in the outbox as limited.
Conserto
Resend it from the outbox screen once the hour turns, or raise the per-channel limit in the notify settings if the allowance is too small for the application.
