Practical checks
Check subscription, saved app and connection identifier. If you already requested a reload, read its result before resending. Follow the dedicated guide for a fully empty playlist; a missing category can instead involve package settings or filters.
Prepare information before making changes
A useful example: “Samsung, SmartIPTV, connection 1: the list appears, but two channels have no sound since 19:10. Other channels work. I restarted the app and have not resent a reload.” Say whether the issue is an empty list, buffering or a licence error. Photos should show the message without PINs, passwords or QR codes.
