My Question or Issue

 I have a lot of songs (not sure of the exact number) saved to my 'Favourite Songs', and all of these songs show when using the Web Player and the desktop application. However, when I look at my Favourite Songs on the Android app, it says there's only 47. These 47 songs are all ones that I have added to my Favourites - there's some songs that I added a few years ago, and also some that I've added more recently, but there's a lot of songs missing.

Is there any way to see all of my saved Favourite Songs on mobile, or are they only accessible on the Web Player/Desktop?

Thanks, and apologies if this has already been asked.
