All charges for subscriptions (premium channels, etc will be there) in your dashboard..
While you are at, you probably should change your password to the email account that is visible on that invoice. Some snooper probably saw some Roku related info in that email box and generated the phony invoice.
Also, you should go back and EDIT your post (those 3 dots to the right of the message box) and either remove the active link or post a screenshot of that invoice instead with your info removed.
Highly suspicious. I would contest that charge with PayPal and make them provide details. My guess is they can't, at least anything legitimate.
