Hi, Helen,
I tried to add the license key to my NAS by following the instructions on
https://help.resilio.com/hc/en-us/articles/204762369-How-to-activate-remove-a-license-seat-
But nothing happens :-(
I am using a Synology NAS (DSM 6.2.1-23824) and Safari (Version 9.1.2 (11601.7.7)) on El Capitan.
Do you have any idea, what I could do?
Thanks in advance, Michael
