LMS 8.0.0 + Radio

Hi

installed LMS 8 on QNAP (using QLMS 2): Logitech Media Server Version: 8.0.0 - 1583188601 @ Mon Mar 2 23:54:19 CET 2020

Now connecting with one of my 3 radios does not work - Message: xxxxx needs to be updated to a newer version of Logitech Media Server
When connecting with my Boom, Transporter, Squeezeplay - everything works fine.

Then I tried the same on Windows 10 - When using LMS 8.0.0 - same problem occurs
Going back to LMS 7.9.3 everything works fine again.

Radios do use the version 7.7.3 r16676. I did not find any newer version for baby.

Any hints?
