Purchased 3 premium licenses, says it should be eligible for multiplatform

[Rokkahorra 0]

Am I misunderstanding what is meant when it explicitly says 

"Following products are eligible for activation with this multi-platform license:

Download for Windows
ESET Smart Security Premium
ESET Internet Security
ESET NOD32 Antivirus

Download for macOS
ESET Cyber Security Pro
ESET Cyber Security

Download for Android
ESET Mobile Security
ESET Parental Control
ESET Smart TV Security

Download for Linux
ESET NOD32 Antivirus for Linux Desktop

underneath the description for smart security premium product? Doesn't that mean one of these license keys should be able to work for NOD32 Antivirus for Linux Desktop? Because I purchased 3 licenses of the premium package and cannot activate/verify subscription for the linux box because it uses the legacy User/PW instead of the license key.
