Not reliably, based on YouTube’s published instructions. YouTube does not document a universal way to complete a paid channel-membership purchase in the standard smart-TV app while watching a 24/7 livestream. It says the Join button is unavailable on some platforms. If you do not see Join on your TV, use the channel’s homepage or its /join page, or finish the purchase on YouTube from a computer or mobile device.

That is a limit in YouTube’s documentation, not proof that every TV app blocks membership purchases. A TV app may show Subscribe, but subscribing to follow a channel is different from paying for a channel membership.

What to try on your TV

  1. While the stream is open, check the channel or stream page for a Join button. YouTube notes that Join is not available on every platform, so not seeing it does not necessarily mean the creator has no memberships. YouTube’s membership instructions describe the platform limitation.

  2. If Join is missing, open the creator’s channel homepage or visit the channel’s /join page. You can also use YouTube on a computer or in the mobile app.

  3. Sign in, select Join, choose a membership level, review its perks, and follow the payment prompts to complete the purchase. The channel must have memberships enabled, the feature must be available in your country or region, and you must meet YouTube’s age requirement: 18 in most locations, or 19 in Korea and Algeria, according to YouTube’s membership instructions.

Why Subscribe and Join are different

  • Subscribe follows a channel; it is not a paid membership. YouTube’s TV-app instructions describe revealing video details and choosing Subscribe while watching a video. YouTube’s TV-app guide does not establish that this action buys a creator membership.
  • Join starts a paid channel membership, with monthly payments for creator-defined levels and perks. Perks can include badges, emoji, posts, or members-only content; what is offered depends on the creator. See YouTube’s membership-benefits guide.
  • YouTube TV membership refers to a separate live-TV service, not a creator’s channel membership. Similarly, YouTube’s instructions for buying movies and TV shows on supported TVs do not show that channel memberships use the same checkout. YouTube’s smart-TV purchase guide covers those film and TV purchases.

Can you join without leaving a livestream?

YouTube documents a membership purchase during a specific live-viewing flow: the mobile app’s vertical live feed. In that feed, tap the dollar-sign icon in live chat, tap Memberships, then tap Join. YouTube says this purchase route is available on Android phones and is not currently available on iPhones. Those instructions do not establish the same flow for a standard horizontal livestream or a smart-TV app. See YouTube’s vertical-live-stream guide.

YouTube also says that when someone joins during a channel livestream, a green “New Member” message can appear in live chat. That confirms a live membership interaction, but it does not document smart-TV checkout.

If Join does not appear

  • Try the channel homepage or its /join page: this is the direct alternative when the TV platform does not show Join.
  • Switch to YouTube on a computer or mobile device: YouTube recommends these platforms when Join is unavailable on the current one.
  • Check eligibility: the channel must offer memberships, and membership availability is limited to eligible countries or regions. Viewer age requirements also apply.
  • Do not treat Subscribe as a workaround: it follows the channel but does not purchase a paid membership.

For creators running a 24/7 stream

A viewer’s ability to buy a membership depends on YouTube’s interface and eligibility rules; keeping a stream running does not guarantee that Join will be available on every device. If your separate goal is to keep uploaded videos looping as a YouTube livestream, StreamNeo runs that stream from the cloud: upload your video or build a playlist, add your YouTube stream key, and go live. It is YouTube-only and does not stream from a camera.
