Home Internet Gaming Problem

We are having the exact same problem as all of you. Can't stay connected to any mutliplayer game for more than a few minutes. Began around the first weeks of December 2022 for us. Complained to local store in January, sent us to customer service, and the girl I got just straight up told me that she didn't think TMobile was going to be a good option for gaming from now on. I was in shock. We've been with them since they rolled out home internet, and have all our cell phones through TMobile. It was like "see ya. You were in while it was new (read: good)." I'm glad some of you got a tech rep who has provided a little hope, but I'm wondering if they aren't leading you on due to some deliberate blocking we noticed.

We identified the issue as being the high latency spikes that weren't present previously as the culprit by using a variety of tools. Everything else works, so we bought ExpressVPN hoping it would smooth out the ping. We tried the DNS for the console ExpressVPN gave us but it didn't help. Then we set up a hotspot on a laptop (had to use a third-party app, Dynu I think, in order to register it on Express). Once it was set up, I connected the console, and it was immediately SHUT DOWN BY VPN BLOCKERS. This was proved bc on the laptop we could get any website EXCEPT ones even remotely connected to VPN services. Surf Shark, Nord, even Fubo (!) were all blocked. TMobile is aggressively stopping consoles from accessing VPNs from what we experienced. We felt like we were just given a pink finger.
