Start track mix from favourite track instead of favourite playlist

When I click on a favourite track, I’d like that it starts a track mix instead of playing all my favourite tracks...

It seems when I chose “Start track mix” on the website, it works as expected :

first play the selected song then onto a track mix

But on android app, chosing “Start track mix” on any given favourite track just starts a track mix without my initially selected song
