CM3000 not receiving full speed after upgrading to 2gb tier

Hi all.  Spent a couple hours with chat support trying various things, but my modem is stuck at 1400 down and 40 up after upgrading from the 1.2gb tier to the 2gb tier after it recently became available. 

I have 32 QAM256 channels locked, 2 OFDM channels and 1 OFDMA channel locked. locked. Low level support and AI agent say "all works as expected".

Looks similar to the problem described at: ‎CM3000 not receiving full speed after upgrading to 2gb tier | Xfinity Community Forum

Looking for guidance.
