Shipping Status: Arbitrary Delivery Failed

[guest4]

One or more of our stores occasionally shows shipping statuses of "Delivery failed." If you click on the tracking numbers and follow the link through to the delivery service's Web site (e.g. FedEx, USPS) the shipment could be in any fulfillment state, but not necessarily a failed state.

We are hoping to get some clarification from the community:

• Has anyone seen a similar issue?
• Is there any reason to believe that these statuses are correct?
• What circumstances must arise in order for the "Delivery failed" status to appear?

Here's an example:

Fulfillment status is "Delivery failed" but the actual parcel is "Out for Delivery" with USPS.

Here's another example. Shopify reports that the delivery failed but USPS says it was delivered.

Same thing keeps happening for me.. since mid 2023. After updating the tracking link from others to USPS. it randomly shows "delivery failed" when the actual tracking link shows correct status - in transit, out for delivery and etc. I have to literally cancel each  fulfillment and re-added the tracking number, it shows correctly but that would change the order fulfillment date in the order. It looks like this error is mainly happening with USPS but after shopify update their admin look and features in 2023. 

Shopify was contacted for this error and they asked me to contact USPS to investigate. How? the tracking on USPS site is correct. I just could not believe shopify asked me to contact USPS to fix this (for them?)..
