Troubleshooting: tracking, pairing, saves and audio
Work down the list rather than sideways: almost every problem in this game is network, latency or account.
Most Just Dance: Decades of Hits problems fall into four groups: the phone cannot pair (network or client isolation), scores feel random (latency or phone placement), players drop mid-routine (Wi-Fi signal), and songs are missing (account ownership or an unfinished sync).
Just Dance problems look random and are almost never random. They cluster around three systems: the local network, the display chain, and the account. Work the relevant list top to bottom before trying anything clever.

The phone will not connect
| Check | What to do |
|---|---|
| Same network | Confirm the phone and console are on the same SSID, not one on Wi-Fi and one on cellular |
| Guest network | Guest SSIDs often block devices from talking to each other; move the phone to the main network |
| Client isolation | Router settings that isolate wireless clients break pairing while leaving internet access working |
| Band split | If the console is on 2.4 GHz and the phone on 5 GHz with separate SSIDs, put both on one |
| App version | Update the Just Dance Controller app; it is a separate app with its own releases |
| Console side | Restart the console's network stack; a console that has been on for weeks holds stale pairings |
Client isolation is the invisible one. If the phone browses the web fine but never finds the console, stop looking at the app.
Scores feel random or unfair
This is a latency problem nine times out of ten, and it has a fixed order of fixes:
- Turn on your television's game mode. Picture processing adds delay between what you see and what you do, and in a rhythm game that delay is the difference between a good and a bad grade.
- Stand the phone up and face it at the room. Load-bearing detail: a phone lying flat, in a pocket, or propped facing away reads almost no movement.
- Get on 5 GHz if your router splits bands, and get closer to it.
- Reduce what else is on the network. A house full of streaming devices competes for the same airtime.
- Test with a slow, big-arm routine. Uptown Girl is the calibration song — large readable shapes, forgiving timing. If Uptown Girl scores badly, the problem is the setup, not the dancer.
Players drop out mid-routine
Dropped slots during a song are almost always radio, not software:
- Signal strength. Phones at the far end of the house, or behind a wall from the router, drop first.
- Battery saver. Some phones throttle background networking aggressively at low battery; a phone at 15% may become unreliable.
- Thermal throttling. After a long session a phone gets hot and starts cutting corners. Rotate which phone is in play, or let it cool.
- Access point limits. Consumer routers handle a surprising number of simultaneous clients poorly; six phones plus a console is a real load.
Songs are missing
Two causes, and they fail differently — see the install and unlock guide and the cross-edition library guide:
- Owned content missing: the older edition is not installed, or the purchase is on a different profile.
- Subscription content missing: Just Dance+ has lapsed or the connection dropped; streamed songs are not stored locally.
Progress and Dancer Cards reset
Cards and levels live with the profile data. They survive ordinary restarts but not always a reinstall, a console migration or a profile deletion on the console. If the card was attached to a Ubisoft Account, the progress has somewhere to live and usually returns after signing in; if it was local-only, it may not.
The prevention is dull and effective: sign in before you build a card you care about. The dancer cards guide explains the attachment.
Audio problems
- Music and prompts out of sync: check the television's audio pipeline — soundbars and receivers add their own delay. If your TV has a game mode that covers audio as well as video, use it.
- No audio at all on a receiver: pass-through settings on modern consoles are a common culprit; the console's own audio output menu is where to look.
- Sound effects drowning out music: the game's in-game audio menu generally has separate music and effect levels.
When to stop troubleshooting
Three symptoms are worth escalating rather than fixing on your own: a console that crashes back to the dashboard during a routine, a save file that corrupts repeatedly, and an account that will not authorise purchases. Those are Ubisoft Support or platform support issues, and nothing on this site can touch your account. For anything else, the FAQ answers the questions that come up most in the first week.
