Hi mcadenhead, this usually happens when the Roku app hasn’t fully synced all devices to your account for voice integrations. Try these steps:
Log out and back in: Sign out of the Roku app, then sign back in to force a full device refresh.
Check device registration: Make sure both TVs are registered to the same Roku account and show as “Active” under your account on my.roku.com
.Reboot the TV: Power-cycle the TV that’s missing from the app, then reopen the Roku app. Update the Roku app: Ensure you have the latest version installed, as older versions sometimes fail to sync multiple devices. Re-link Alexa: Once both TVs appear in the app under “Devices in Account,” try re-adding Roku in the Amazon Alexa app and discover devices again. If it still doesn’t show up, contacting Roku Support can help refresh your account and resolve hidden sync issues.
