A few Spotify settings can override Attunify's own picks:

• Shuffle — Attunify turns this off automatically once it takes over playback, but worth a glance if something looks off.
• Smart Shuffle — a separate toggle from regular Shuffle; if it's on it can occasionally slip in its own pick instead of the next track in your list. Tap the shuffle icon until it's fully off (it cycles Off → Shuffle → Smart Shuffle).
• Automix / Crossfade — Settings → Playback.
• Mix — the toggle inside the queue view itself.

Right here — the entry above covers exactly what that popup said. Untick "Don't show this again" isn't possible from here, but nothing's lost by ticking it; this FAQ has you covered either way.

Position is calculated from a full pass over your listening, not recalculated on every play — so it moves once daily rather than in real time. The sparkline/graph next to each track shows the trend over recent days.

It overlays the average chart position across all Attunify listeners on top of your own — a quick way to see whether a track's popular with everyone or mainly with you.

Mixes are cached for 24 hours per person to avoid hammering Spotify's API — they rebuild automatically once that window's up, so you'll see new picks the next time you check in after a day's passed.

Radio mixes blend tracks you already like with new ones found via two outside music-data services. Those services occasionally have nothing useful on an obscure or older track, so it can slip through without being checked against the mix's genre. It's rare, and it only affects the "new" tracks in a mix — never the familiar ones from your own Liked Songs. If you spot one, the Feedback box below is the quickest way to flag it.

Attunify picks up what device you're playing on when it launches. If you switch devices afterwards, either select the new one manually from the Playing on dropdown (settings menu), or restart the app so it picks up the change automatically.

The Feedback box right next to this FAQ link in the settings menu — type it in and hit Send, no email needed.

These come from a system notification, which needs the notification permission Android asks for the first time you open the app. If that prompt got dismissed or declined, lock-screen/notification-shade controls won't appear — playback itself still works fine from inside the app either way. Fix it in Settings → Apps → Attunify → Notifications and turn notifications back on, then reopen the app.
