Flint without FTP and NFS option

Hi, I have a router Flint, update to the latest stable version of the firmware, 4.1 but I don’t have the FTP and NFS sharing option, the following is the screenshot of what I have:

I can move the file with Samba or WebDAV but I’m wonder why I don’t have the other options.

I also have some issue with the DLNA server, but I will try to solve it on my own and in case, open a new Topic.

Thanks in advance.

FTP and NFS still have some problems that need to be resolved before they are supported.

fair enough, and thanks for your answer.
I asked because from the two feature are already published as part of the 4.* software version, at least from your online documentation.
Have a good day!
