Chihiros Magnet Light (first version)

[PixelArt]

Hello, I just bought three Magnet Lights.
Only one can update to version 22.
For the other two, which are on version 1, when I try to update, the app tells me: "No updates."
What should I do, please? I tried with another phone and it's the same result. I tried unplugging and plugging it back in several times, and it's the same.

Different production batches have different firmware versions.
If there is no updating notification, there is no new version.
