Hello!
Just do not go any further, the NC11 runs without problems and can also share data with link etc …
I make the update to the most recent version of 12 missing this share button completely, no matter in which browser synonymous always.
System: Ubuntu Server 16.04.1, Apache2, php7.0, mysql, all up-to-date
Also find nix if in Google search to these errors, also in English.
Otherwise, the NC12 works problem-free and runs very well, except the button for data to divide is missing and apparently not possible.
Regards
Johann
