Update:
Not sure if it is a local tower issue or due to the carrier package 20.1, but I am not holding on to LTE like I used to in rural areas. On a 15 mile trip through the country where I used to have LTE the entire trip, I saw both 3G and 1X. Reported in the sprintzone app, but I can say I am not super happy about it.
I still grab solid B26 inside my house, so not all is lost.
