To be honest, I'm not sure what mechanism the Microsoft store uses to determine if a user is licensed or not. In my code, I just use Microsoft's framework to tell me if the user is licensed or not. Very few users seem to run into issues with this, and I assume the majority don't have internet access at their venues. I think as long as you log into Windows using the same email address you used to purchase the app, there should be no issues with the app licensing. Having said that, the FastSpring store version of MobileSheets (https://zubersoft.onfastspring.com/) uses my license server to validate the purchase, so I have complete control over how that works. There are only a couple of license checks required and then internet access is no longer needed. The major limitation with the FastSpring version is that it uses a license key and that key can only be used on a single device. If you want more information on this, or want to discuss switching over, email me at mike@zubersoft.com.
