Anyone else have this problem and/or could offer any solution?
When using WiFi with t-mobile home internet, YouTube on my phone, tablet, and wife's phone are barely usable. Nearly all videos stop after a few seconds and then the app just tries to buffer the video with the spinning arrow showing. No amount of waiting will restore the video. If i switch the phone to cellular data the video will start again. Related to this, YouTube smart downloads is continuously active. All of this happens only while using T-Mobile 5g home internet, not on our AT&T internet.
This never happens while using cell data connection on the phone (T-Mobile is not our cell carrier). It also doesn't happen with any other streaming device, Roku, computer, etc, or any other streaming service, Disney, prime, etc.
Download speeds are extremely high. That's not the problem.
