We have not set a limit to the amount of VPP tokens that can be used, normally, only one token would be sufficient for your complete environment.
However should you have your VPP Apps divided over multiple accounts, you can just use them within Xinca Management System.
On the other hand, when you have multiple Xinca environments, so a Parent School with Child Schools, you’ll only need 1 VPP token.
You can just upload this token in all connected environments.
Again, multiple tokens can be used.
