I have two units Dwarf, to authorize paid plugins on both unit , I had to contact Gianfranco because it’s done manually on his side.
But there was an issue with third party plugins, here is what said Gianfranco
" The licenses for WOW, TTAP. MEGA Calif. and LP3 Basic are stretch goal licenses and cannot be applied to additional devices. For those plugins you’ll need to purchase if you want them also on the 2nd. unit."
To copy one setup to the other device it’s very easy, just use the backup export/import option via the usb key.
