Work through the checks
- Test whether the channel list and playback still work.
- Compare the same national feed and date with the broadcaster schedule.
- Check automatic time and the player’s guide-source settings.
- Use a documented refresh and report missing ranges or a consistent offset.
Do not apply a manual time offset to solve a completely blank guide.
Send the useful details
Tell support the actual device model, OS, player and version. For playback, name the item and time zone. For an order, use the receipt reference. Keep passwords, private playlist URLs, device keys and full payment details out of public screenshots.
