Hello,
Our team continues to investigate issues related to delayed carrier notifications. As mentioned previously, there is no impact on "Order Confirmation" or "Return Initiated" notifications. At this moment, notifications should not see delays greater than one hour. We are actively working to resolve the matter as soon as possible.
Our next scheduled update will be at 9:00 PM PST, or as soon as the issue is successfully addressed.
Sincerely,
Narvar Support
