Avid eucon s3 + cubase 12 solo clear botton not work

In my new version of cubase 12 my Avid S3 not work the botton Solo Clear like in Cubase 11, why? thanks.

I SOLVED, THE PROBLEM IS THE APPSET
C:\Users\<USER NAME>\AppData\Roaming\Euphonix\UserSets\MC2User\MC_USER_SET__Root

AND COPY THE Cubase11.xml to Cubase12.xml and open in an editor like notepad and replace the name Cubase11 by Cubase12 in all content, and change
<AppVersion>11.0.0</AppVersion> to <AppVersion>12.0.0</AppVersion>

AND I WILL CHANGE TOO OPTIONALLY
<Notes>Cubase 11.0.0.229+ EuCon Artist Series Appset, Adapter 7.3.0.06+, incl.API3+S3+S6 Support</Notes>
TO
<Notes>Cubase 12.0.0.000+ EuCon Artist Series Appset, Adapter 7.3.0.06+, incl.API3+S3+S6 Support</Notes>
