Just happened to me, fedex said I’d get a package today, it was just changed to next Tuesday.
A few months ago I ordered 6 bags of salt for my pool. The delivery dates changed daily until it said the packages were lost.
Filed a claim and got a refund. 2 weeks later my local fedex depot called me...
Here is the ad from that dealer, they list it as a PP2. Window sticker is attached
