Is it possible to install the netclient service manually. Netclinet on Synology no longer works on 0.14.3 as the join command no longer installs the daemon, I think.

Failed to restart netclient.service: Unit netclient.service failed to load: No such file or directory.

Use -daenon install flag with join command

Thanks @bored-island-21407 --daemon install after the access token worked perfectly. Updating as expected on Synology
