Welcome, and thank you for posting here in the Roku Community, @elephanttv!
We appreciate you informing us about the availability of Season 1 of the series Upright on The Roku Channel. We'd be happy to share further information about this.
Currently, Season 2 is the only Season available on The Roku Channel. No worries! I'd be happy to share this with the team for review.
In the meantime, you can update or change your subscription directly from AMC+ to stream on your Roku device. After making the subscription changes, you can access the app directly from the standalone app as well.
You may refer to this support article to help you: How to add apps to your Roku streaming device
Hope this helps!
Warm regards,
Carly
