Can't chromecast streaming services on T-mobile Home Internet

I've spent multiple hours on the phone with tmobile, and google. (The first time it took them 6 hours to call me back because I lost my place in line) I can't get any of my google smart home devices to work with the tmobile modem/router. I factory reset 5 google home devices and reset them up with a mobile hotspot instead of the tmobile internet(suggested by google to troubleshoot) They had no issues and worked fine. After factory resetting those same devices they will not work with T-Mobile's equipment. This is the second 72 hour ticket I've had to put in for this. (The first time (over a month) I never received a call back and the issues never got fixed). If T-mobile is going to charge me for a service that I cannot fully use this is a problem. I had no issue with this issuing my own personal cable modem and router. Even T-Mobile's iPhone hotpot worked. The tmobile tech said that is new technology...but so far I'm unimpressed. Where's my compensation for the time I've wasted and a service/equipment that doesn't work properly?

I have Chromecast with Google TV, a Nest Mini Speaker, a Home Mini Speaker, a Nest Thermostat, an Echo Dot Speaker, 3 Phillips Hue Smart Bulbs, 4 Geeni Smart Bulbs, 3 Wyze Surveillance Cameras, and 1 Wyze Lock.

Sheesh!

Everything works fine, EXCEPT my devices that have the Google Assistant attached to them. This even includes my Pixel 4 XL.

My Chromecast with Google TV will not let me use the assistant on the home screen. Because this is Google TV I'm not casting from my mobile phone. But I do appear to have connectivity issues using Hulu. Netflix and YouTube seem to stream just fine. In fact once an app has started streaming, the Google Assistant seems to work okay within the app. But for some strange reason when you go back to the Google TV home screen it loses the internet connectivity to use Google Assistant.

I'm experiencing the same problems with my two Google speakers. Every time I use the wake word, the Google Assistant will tell me that there was some type of "glitch" and to wait a few seconds and try again. 

Hey T-Mobile, there's clearly an undiscovered link between Google Assistant and the T-Mobile home internet service. All my other smart products seem to work just fine. But all my Google Assistant products cannot maintain a solid and consistent connection. I've experienced some luck with disconnecting and reconnecting the affected device, but that work around is not consistent.
