Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
Only way to have two roku on the same account is by using the same email address when activating it, if you used a different one you have to factory reset it and use the same email as the first. When connected if you erase a channel or app an one it happens on the other as well.
i installed a roku on a second tv and did not go here to crosslink the two. Can I connect these two still?
By crosslink, do you mean where both Roku devices have the same channels installed? As @Tivoburkee mentioned, that is done by attaching both Roku devices to the same Roku user account. If they are currently connected to different user accounts, then you must do a factory reset on one of them and link it to the same account the first one uses. There's no way to change their linked account other than a factory reset.
