Remote for Web player not working

The chromecast icon on my android phone lets me choose the web player on my laptop. If I then try to use the remote functionality, the four directional buttons and the back button are not really doing something. However, clicking on the home icon does bring you back to the home screen.

Also, the volume is not adjustable through using the volume buttons of my phone (while they are usable when using a chromecast for example).

Is the remote supposed to work with the new layout?
