Five things that explain almost every report
The player will not play the card you made
Almost always the chip. Only MIFARE Ultralight EV1 · 48 bytes · MF0UL11 is played; NTAG213, NTAG215, NTAG216, the 128-byte Ultralight EV1 (MF0UL21), Ultralight C and MIFARE Classic are not, and no app can change that.
If Milvo made the card, the chip is already right — the app refuses to write any other — and the read-back proved the link. Then the answer is in the next panel.
The card is written, but the player is silent
Usually with a red stop sign. The card is fine — the player doesn't know this playlist yet. A copy plays only a playlist the player has already seen from the MYO card, and it can't introduce the playlist itself:
- Connect the player to Wi-Fi and put the MYO card in. A cloud appears, then it starts playing.
- Wait a few more seconds, then take the MYO card out. The player now knows this playlist — and you can always check in the Yoto app whether the player already sees it.
- Put the new card in. It plays like the original.
Do this once on each player the cards are used with.
Listening without Wi-Fi is a separate thing. For that the player has to download the playlist: leave it switched on, plugged in and on Wi-Fi, with no card in, for a few minutes up to a quarter of an hour. You can follow it in the Yoto app. At home on Wi-Fi the cards play without it.
This is the single most common "it does not work" that turns out not to be broken.
Nothing happens when you hold the card to the phone
Check that NFC is on, then move the card slowly across the back of the phone: the antenna is a small area, and on many phones it sits near the camera rather than in the middle. A thick case can be enough to stop it.
You lifted the card during a write
Hold it there again — nothing is broken.
The app rewrites every page from the
start and finishes the job. This is true at every point where a write can be interrupted.
The card shows no playlist name
A missing title is a normal outcome, not a failure. The name is fetched from a public page and that lookup is optional — if you turned that setting off, or the page did not answer, the card is still correct. The link is what the player reads, not the name.
What to put in a report
The app can write most of this for you: the help screen composes an email with the chip type, the card's serial number, its settings bytes and the result of the last operation already filled in — with the card's token masked out, because that part is nobody's business, including ours.
Adding these by hand helps too:
- Phone model and Android or iOS version.
- What the packet of blank cards claimed the chip was.
- What you saw on screen, in your own words, and at which step.
- Whether the MYO card has been in that player since the playlist was linked.
Refunds and purchases
The unlock is a one-time purchase handled by the store you installed from. Google Play can refund it directly within 48 hours; after that, or on the App Store, write to us and we will sort it out. The full policy is on the terms page.
Changed phone and the unlock is missing? Use "Restore purchase" in the app — it asks the store, which is where the purchase actually lives.
Privacy
Milvo has no accounts and no servers of ours, and the app sends nothing about you anywhere. The details are on the privacy policy page.
Checking a card is free, unlimited, and never writes to it.
