T-Mobile and/or YouTube incorrectly throttles 1080p high bandwidth videos on youtube.com in the web browser for ALL T-Mobile customers. (even with any video optimization settings turned OFF)
If you are a T-Mobile customer you can see this for yourself right now -- on your cell phone or tethered computer navigate in your web browser to youtube.com (do not use the YouTube app).
Search for any VEVO music video (since they use more than 1.5 mbps bandwidth).
Play the video in the browser, and change the resolution to 1080p - the video will freeze and buffer continously since the stream is capped at 1.5mbps.
I am working with T-Mobile's Office of the President and their engineers where I discovered the issue and I did calls with them and testing at home and in store with multiple devices to confirm.
Hopefully T-Mobile and/or YouTube resolves this soon.
Can I get T-Mobile customers to reply to this thread and confirm they see this issue?
