Why don't I always see ads?

Ad display is controlled entirely by YouTube — based on the video owner's monetization settings, autoplay behavior, your region, and your YouTube account. Mixtuby does not block ads. They may appear at any time.

How do I listen with the screen locked?

Sign in with YouTube Premium. As of 2026, YouTube restricts background playback on third-party sites for non-Premium users. With Premium, Mixtuby unlocks background playback automatically — including lock-screen controls and Bluetooth headphone buttons.

You're offline

Playback requires an internet connection. Your playlist and position are saved — music will resume automatically when you're back online.
