Card won't download into device

Hi, new Yoto Mini user here!

I have 5 tracks in a MYO card. Been trying to get it downloaded into the device since a day ago. Popped the card in, waited till it played for a few seconds, then took it out. Card playlist appeared under "Downloading" but 0 out of 5 downloaded for the longest time. Left it to charge next to my router. Woke up and saw in the app that it's under "Not downloaded".

Popped the card in again and repeated what I did the night before. Same thing happened: from "Downloading" to "Not downloaded". Any ideas how do I fix this?
