I bought a paid license for, but ads started showing again - or license on other devices

Maybe you have uninstalled the small @Voice Premium License - a license only app for @Voice. Or maybe you got a new phone or tablet, and did not install it yet. Please open Google Play and find "@Voice No Ads Upgrade" there, or press this link:

If you see a green "Install" button - install the license app back and the main @Voice app will stop showing ads. If Google Play says you have to buy it again, you have probably changed your Google (Gmail) account, the phone is activated with a different account from the one under which you purchased @Voice No Ads Upgrade. Here is what to do:
 
On your new phone, go to Android System Settings – Accounts – press “Add account” – press Google – add your old Gmail account there, as an additional account that this phone knows. Then go back to Google Play Store app. Press the round button at top-right representing your account, then press to select your old Gmail address. Now you will be able to download all paid apps that you have purchased under old Gmail address without paying again. Install “@Voice Premium License” app and then the main @Voice will no longer show ads on this device. In a similar way you may now install other paid apps and items from Google Play without paying again.
 
If you just purchased the license on another device, and the second device uses the same Google account, but it still shows the Buy button instead of Install - please wait for a few hours. Google needs some time to sync the purchase data between devices.
