Not working the code to Play Store

Hello there,

I have noticed that the app doesn’t recognize the apps of the Play Store.

Before it was all great, but now it looks like this:
“↻ The app was not found in the store. 🙁”
https://droidzon.com/lista-top-mejores-antivirus-android/

The code of the app is correct. I have re-install the plugin, deactivate the other plugins and even delete the cache of the page to see if that solve, but…
Nothing seem to work.

Any idea?

wordpress version 4.9.5
WP-Appbox version 4.0.43
