High-Speed Internet Gateway does not work with some apps on T-mobile Home Wifi Internet

Hey. So I just got my 5G LTE Gateway for the T-Mobile home internet (on a Business plan) and ran into the same issue (couldn’t access any streaming service). 
 

I called 611 and was transferred 3 times before ending up at an internet specialist. He was able to determine that there was a content filter (that was automatically applied due to the plan being a business plan) that prevented access to websites that T-Mobile considered to be non-business essential (like Netflix, HBO, Hulu, Crunchyroll, Funimation, etc.). He disabled the content filter, synced the equipment and bam. Now all streaming services work, as well as online/multiplayer gaming (XBOX, PLAYSTATION, PC, etc.). 
 

So it's a heck of a lot easier than worrying about DNS signals and IPV4 or IPV6 or adding a VPN. Just call and have the content filter removed.
