Multi-device access is most useful when it reflects real viewing habits. Assign each connection to a regular screen, use clear device names, and sign out of equipment you no longer own.
Keep performance predictable
Wired Ethernet is ideal for fixed televisions. For Wi-Fi, place the router away from heavy interference and use the 5 GHz band when range allows.
Protect the account
Share access only within the permitted household or team, use a unique account password, and contact support promptly if credentials may have been exposed.
