Push notification test don't work - help


I have a problem with test ionic pusch notification

I make an app, I follow all the tutorial step
I have 2 buttons , when I press “register for push” I correctly receive a token reply

SO I run the app on my android device with same result
After this I’m open the console https://apps.ionic.io I try to test the push to every body, but when I press search no one is found why?

Thanks for your support
