No compliant device for an application I just uploaded

Hello,

​

I'm currently developing a small watchface for Android Wear smartwatches, and my app was finally published by Google.

But I can't download it on any of my devices, even if I have it running on my smartwatch.

Here is the link to the app on Google Play: https://play.google.com/store/apps/details?id=fr.oupsman.moonphase

​

The source code is published here :

https://git.oupsman.fr/oupsman/wear_moonphase.git

​

To publish it, I've generated a key to sign the file, and using Android Studio, I create a signed app bundle using this key.

After a few days, Google finally accepted my app, but I can't download it, nor can my son who also has a compliant device.

As I'm quite new to android dev, I have no idea what I did wrong.

​

Any help would be appreciated.

Thanks a lot.
