Connection error for My_favorite when use twice

Hello,

  1. I clic on “net radio”, it works
  2. Search for a specific radio and add it to Net Radio favorit… it Works
  3. Come back to the net radio menu
  4. Choose “my favorite”… it works
  5. Come back to the general menu, and choose “Tuner / FM”… it works
  6. Come back to “Net Radio” “My-Favorit” (sames as point 4). I receive the message “connection error”

IU have to turn off the tuner (Yamaha CRX_N470D) and go back to the Net Radio / My favorite… it works

So, i can only go to “my favorites” once.
After that, I always receive the same message “connection erreor”

Do you have an idea of what to do ?

Thanks
