If such a real time map exists, I've never been able to find that with the tracking numbers of the major delivery companies. Many services (Door Dash, some cleaning services etc.) do provide such real time maps but I'm not sure that USPS, Fed Ex or UPS do.
I can sympathize with the member that it is a pain having to wait around for a deliver that can come any time between dawn and sunset. Nothing to do about that for this delivery, but many members are offering constructive suggestions as to how to handle it in the future.
