For a month now my now tv is stuttering (sound) and buffering. I cast to chromecast. Internet speed is fast and I've no problem casting other apps including btsport! I've heard this is nowtv servers?! Sort it out @nowtv, expensive enough as it is, youd expect it to work properly!!!
Tried deleting and reinstall the app?
Unplug your router for a few minutes?
Head onto live chat and explain the fault, as we are just customers here. Make sure to click “chat online”.
What about using your phone data as a hot spot just to test it?
If that all fails I would send an email to customer support to report the faul, where you can send videos/pictures.
