I have a Discovery + subscription that I can access on my TV. How do I access it on my mobile device?
How did you subscribe to Discovery+?
Through my TV.

Premium subscriptions purchased through 3rd party systems like Roku, Amazon, Hulu, Smart TVs, etc, are often only viewable via the service through which you subscribed. In Roku's case, most (all?) are viewed via The Roku Channel.
If you want to view on all platforms supported by that channel you typically must subscribe directly with the channel via its web page then use its dedicated app for each platform, authenticating via your channel account.
