Pixel 4a 5G - Only connects to LTE not 5G

Was wondering if anyone else is having an issue with the Pixel 4a on 5G.  I just upgraded my Xfinity to an Pixel 4a 5G and unable to connect to 5G.  When I look at my plan on the APP it still shows that I am on the unlimited LTE plan.  I ordered the phone straight from XFinity.  Anyone else had this problem?  I tried to reset the Network settings but no luck.  When I go to SIM details it says LTE Data.  I know I am in a 5G area as my coworker who is on Xfinity with our iPhone gets 5G.
