Can I share my amc+ account with people even if I use “amc+ on the Roku channel” and if I can share my account how do I because as far as I know I don’t have a username or password I’m just signed in through my Roku account.
Me too, someone please help
You can only do it if all the devices are linked to the same Roku account. As you've seen, your subscription is only good when using The Roku Channel and that subscription is tied to your Roku account.
One of the advantages of subscribing directly with the provider instead of going through Roku is that you get login you can use on pretty much every device the provider supports.
