I can’t help bypass Netflix Household restrictions or other access controls.
Use the TV within the same household network as the account holder.
Ask the account holder to add you as an extra member if available in your region.
Sign in on a device that is part of the household and use Netflix there.
Update the Netflix app and TV software, then recheck the household setup.
Contact Netflix Support to review your household status or account options.
Consider getting your own Netflix subscription for independent access.
