Hello and Welcome to the Webroot Community!
Paid for webroot complete. When trying to install on Android, it is suggested to purchase another plan. Package says my Android is included in the package. Why should I pay twice?
See here for details and please let us know if you get it installed: https://community.webroot.com/t5/Webroot-SecureAnywhere-Antivirus/How-to-Install-and-Activate-Webroot-Mobile-Security-for-Android/ta-p/199226
