Garmin Express - No map update available (Zumo 595LM Travel Edition)

Hello,

     When I try to update the map on my Zumo 595LM Travel Edition with Garmin express, it says it is up to date (the currently installed map is City Navigator Europe NTU 2020.30) but when I connect my other 2 devices (BMW Motorrad Navigator V and Drive 51 LMT-S), it says the newest version 2021.10 is available and can be downloaded.

    Am I missing something? Why does Garmin Express not offer the option to install 2021.10 on the Zumo 595?

    Thank you!
