Roon doesn't synchronize my favourite song and artist

I added yesterday my favourite artist and song in Qobuz app. They are shown as favs in Qobuz. But Roon doesn’t see it.
I restart my comp with Core, I logout with Qobuz and log in again (at Roon), I push the “synchronize a library” button in Roon, but it is still the same.
Can you help me?
