The panel says “CueUp is not running”?
Then everything is set up, CueUp is just closed. Start it and the panel is back within a few seconds.
The CueUp extension is currently under review by Twitch. Once it is approved, you add the CueUp panel to your Twitch channel. For it to show anything, you need CueUp on your PC — the panel shows what is playing right now. Four steps and you're done.
CueUp is free. Get it on the CueUp page or in the WinkuStore.
Sign in to CueUp with your Winku account and link your Twitch account at winku.de/account. That is how the panel knows it is your channel.
In CueUp, go to “Overlay & OBS” → “Twitch panel” and switch it on. That is also where you choose what the panel shows — cover, the names of who requested what, and how much of the playlist comes after.
While CueUp is running, the panel below your stream shows the current song, what comes next and what follows from your playlist — in the Twitch app too.
Then everything is set up, CueUp is just closed. Start it and the panel is back within a few seconds.
Only what CueUp sends for display — and only what you switched on for it. Viewers never reach your PC; winku.de sits in between. The panel is display only: it plays nothing and controls nothing.
