I'll join in on the thread of people that on a clean install, can't get the latest qpkg 2.0.105 to work for a NAS to NAS sync. Using brand new TS-563 to TS-269L.

Uninstalled the version 2 software and manually installed the version 1.4 software and everything works. Click the "update" button on the app expecting it to install the latest of the version 1 series, but without warning it installs version 2.0.105 and
