Push notifications from LM to iOS and Android devices

[AISystem]

Obviously you didn't add any android device to push app.  The common mistake is to configure android app before LM.
Make sure you are on the same local network as LM. Go to LM android app, edit your user, disable push notification, save then edit and  enable again and save.
Refresh push notification app in LM to see if your device was added. You can then test it directly from the app.

Yes, that turned out to be the problem!

Thanks!
