Match the help page to the country
The US help centre currently carries a Canadian transition notice: Warner Bros. Discovery’s Canadian discovery+ service closed on 17 February 2026, and a new service is provided by Rogers Sports & Media. That is a reason to use the current Canadian provider’s help rather than carry an old US or Canadian instruction across unchanged.
For a viewer comparing services from Australia, an overseas support page establishes that region’s product. It does not establish an Australian subscription offer or prove that a programme is available locally. Follow the country route shown by the provider before entering payment details.
Keep Prime Video Channels and direct access straight
The US Prime Video route uses the Prime Video app and Amazon’s channel-management controls. A direct discovery+ login is a different route. If a paid channel plays in Prime Video but the discovery+ app asks you to subscribe, that may be the documented entitlement boundary rather than a failed payment.
Check the receipt before buying again. For cancellation, follow the organisation collecting the payment. Uninstalling a playback app does not identify or cancel the subscription contract.
Check the actual platform requirements
The current US matrix names Fire OS and Vega OS separately and includes defined Apple TV, Android TV, LG and other television requirements. This is useful evidence that the operating system matters even within one hardware brand. Read the model-specific support page and install from that device’s official store.
When a television lacks the native app, discovery+ suggests supported casting routes or an external streaming player. Use the current instructions for the exact source and receiver. A phone app running successfully does not prove that a TV’s built-in browser is supported.
Troubleshoot the route already purchased
Begin with the same app that successfully recognised the subscription. Test an ordinary on-demand programme there before moving to another screen. For support, record the service country, billing provider, app name and device model. Those details are more useful than repeatedly resetting a password that already works in the purchased service.
Questions about this guide
Does the US Prime Video channel include the discovery+ app?
No. discovery+ states that this channel subscription is watched with Prime Video and does not include separate app access.
Can old Canadian discovery+ instructions be assumed current?
No. The official notice records a February 2026 service transition; use the current provider and regional help.
