Request for Assistance with Issue in Song Selection and Transfer

[Niktheroi]

I've encountered a persistent issue in the Spotify desktop and web applications that I hope can be addressed. When attempting to transfer a large number of tracks from my Liked Songs to a playlist, either by drag-and-drop or copy-paste methods, it seems not all songs are being copied successfully. This happens when dealing with a significant number of songs (500+). The steps I usually follow are: 
1. Have 500+ tracks in liked songs
2. Selecting the first one (most recently added)

3. Scrolling to the last one
4. Shift-click the final song to select all
5. Drag and drop or copy into a playlist (or Ctrl-C + Ctrl-V)
(KO) This doesn't allow for a complete transfer of all selected songs into another playlist. Your assistance in resolving this would be greatly appreciated.
