My Question or Issue

Note: For this issue/situation I'll refer to my playlist as 'Favs' and the other user's playlist as 'Tunes' so it's easier to follow.

When clicking the 'Add to Playlist' button (on iOS you press the three buttons next to a song/album/playlist and then click add to playlist), the songs aren't actually added to the playlist. I have tested this multiple times, and this issue happens on and off with no real pattern as to why. For example, just now I found another user's playlist I liked (Tunes), so I clicked *add to playlist*. When this feature is working, the tracks should all have a green arrow appear next to them or a green tick to indicate they have been added to your library. However, I noticed this didn't happen and so, I clicked on an individual track in the playlist and clicked *add to playlist* (for that track only) and sure enough, my playlist (Favs) did not include the track. I went back into the user's playlist (Tunes) and clicked *add to playlist* again. When selecting 'Favs' there was a pop up saying 'Already added to playlist'  with the prompts 'Add Anyway' or 'Skip Duplicates', despite there not being a tick next to my 'Favs' playlist indicating 'Tunes' was added to 'Favs'.

Sorry this is so wordy/hard to understand, I do have a video of it (split into 2 parts because of file size).

Please let me know if you have any questions 🙂
