FTP extension

Years ago I added the FTP extension to my DOpus license. I no longer use this feature and would like to drop it when I upgrade, but I can't find a way to do this. If I'm not paying any additional on the upgrade because of FTP then I suppose it doesn't matter, but I can't tell if I am or not. So my questions are these:

  1. Am I paying anything additional on the upgrade to v11 due to having added advanced FTP several upgrades ago?

  2. If I am paying extra, how do I drop advanced FTP support?

Thanks.

The add-on is a one-off purchase. You don't pay any extra when upgrading (unless you increase the number of licences).
