Are you receiving the error, "You appear to be connected to an account type at the streaming service that we do not currently support."? This means you have a subscription to that streaming service, but that VidAngel does not link to the type of plan you're using.
Currently, that likely means Peacock's old Basic free plan. To link your streaming service with VidAngel, you will need to have a Premium or Premium Plus plan.
Upgrade your Peacock plan
You can view your Peacock subscription here: Peacock Account. Look at "Plans & Upgrades" and you can then select "Change plan" to upgrade.
