A single channel stalls or freezes
Almost always an upstream feed rather than your connection. Note the exact channel name and message the desk — we reassign you to a different server, usually while you wait.
Everything buffers in the evening
Check your actual throughput, not your advertised plan. HD needs about 15 Mbps sustained and 4K about 25 Mbps. If speeds are fine but evenings are poor, your ISP may be shaping video traffic; a VPN endpoint in a nearby city usually resolves it.
The guide is blank
Refresh the playlist from the portal, then restart the app. If you added an external XMLTV source, remove it — our line carries its own guide data and the two can conflict.
The app says the device is not activated
That is the IBO Player licence, not your USATVStream subscription. Open Activate Device on the IBO Player website, sign in with the same MAC and device key, and pay the developer's one-time fee. Close and reopen the app afterwards.
Nothing works at all
Confirm the credentials were entered against the right playlist type — XC credentials in the XC form, M3U lines in the M3U form. Then contact support; median first reply is 11 minutes.
