Q: I purchased Neutron in Google Play but still getting Trial Expires message?

A: Make sure that Google confirmed your purchase and e-mailed Purchase Confirmation to your Google account. Make sure your device has Google Play Store and Google Play Services installed and working, so you can see your purchases there. Note, sometimes Google Play Services misbehave by providing incorrect reply to the application's request for license validation.

There are 2 ways to try to fix this problem: 

1. Easy: 

  • Reboot device
  • Open Neutron from its page in Google Play Store app
  • Access Neutron's settings -> Help -> Account -> wait until progress bar stops and icon of Google entry becomes green

2. Moderate:

  • Access OS settings -> Apps -> find Google Play Store -> Clear data & cache, additionally you may want to Uninstall Updates and let Google update it again
  • Access OS settings -> Apps -> find Google Play Services -> Clear data & cache
  • Reboot device
  • Open Google Play Store app -> find Neutron -> open Neutron from its page by pressing Open button
  • Access Neutron's settings -> Help -> Account -> wait until progress bar stops and icon of Google entry becomes green

2. Complex: 

  • Uninstall Neutron (backup /NeutronMP with all settings but normally it should persist if it is Android 10 or lower)
  • Access OS settings -> Apps -> find Google Play Store -> Clear data & cache, additionally you may want to Uninstall Updates and let Google update it again
  • Access OS settings -> Apps -> find Google Play Services -> Clear data & cache
  • Reboot device
  • Install and open Neutron from its page in Google Play Store app
  • Access Neutron's settings -> Help -> Account -> wait until progress bar stops and icon of Google entry becomes green

When Google entry becomes green it means that Neutron managed to check license in Google Play successfully and cached it for offline usage. Internet is not required for a subsequent launches of Neutron once you got green icon:

Earlier purchased applications will not be able to check license in Google Play and will behave as not purchased.
