If you are using a Roku account that wasn't originated in the region in which you are using your device, you may encounter issues within a channel. i.e. If you are using a device linked to a different location, in the US or another region.
To resolve your issue, we would recommend creating a new Roku account. Since you're in the US, the account's region will automatically be set in the US as well. If you don't have any extra email address and you want to use the same email you are using at the moment, you can deactivate your existing Roku account then create a new one using the same credentials.
