4 years in on my DW use, but noticed no USPS informed pings on last two orders

For what it's worth, they were both with the same vendor. But that shouldn't matter. I am fully aware of the precautions to make when dealing with Informed delivery. But the last two orders (as stated, same vendor) I got no ping that a package was created, let alone anyone tracking details, but lightning fast T2D as always with that vendor.

Is this a new thing, is there something the vendor(s) can do on their end to no show on Informed delivery?

It's just nice at very minimum getting that "A package has been created" ping to know I don't need to log on to make sure I don't have any pending messages from the vendor.

Informed has been fucked for me for at least 3 weeks now. Out of 10+ packages that have arrived only one popped on Informed before it actually landed.

At least I know I am ot the only one. This purpose is literally the only thing that makes USPS informed useful. I'm still surprise USPS uis alive really. But we all know it will be privatized like everything else eventually. Then we loose all our federal rights.
