How do I add or remove my own YouTube/Twitch stream link?

Open Stream settings of the game you organize, tap Add stream and paste your YouTube or Twitch link into the field “Or paste a link to a running stream” at the bottom of the sheet, then tap Add link. The stream then shows on the match page in the Playbox app. The link appears in the same Stream block as your Playbox streams, as a Stream link row with copy, edit and delete buttons; deleting it removes the stream from the match page. If the link is not a YouTube video or a Twitch channel, you see “Incorrect link”. A pasted link is not a Playbox stream: it has no stream key, it is not counted as Stream #1, #2 and so on, and it is the only option in the sheet once the game already has 5 Playbox streams. There is no separate “Your own stream link” section any more.
