UPS let my package sit in their warehouse for 3 days, then changed my ETA from the 7th to the 10th. The shipment got to San Antonio (my city) on the 8th at 6pm.
This is my current status. My other purchase arrived on the 4th shipping via only USPS. (Both items were purchased 12/31/19)
tl;dr
Never use UPS Mail Innovations
