Can t share playlist Apple Music Reddit

Hi, I just made my first Apple Music subscription (student one)

Ive created a playlist similar to mine of Spotify, and Im having few issues.

UPDATE:

I was not able to create a shareable playlist from my iPhone so I tried through my iPad and surprisingly it worked, but I couldnt see the playlist on my iphone even though its the same iCloud account? I shared the link from my iPad to my iPhone using airdrop and added to my iPhones library but I can not edit it through my iPhone even though its the same iCloud account, what is going on ??

1. Cant I add songs to one of my playlists without adding it to the library ? Or is the library is different than liked songs on Spotify?

2. I cant turn off the add to play list option in settings, when I disable it it automatically gets back to enabled status

Most important:

1. When I enter my playlist and I press the three dots I dont have a share option ? How do I share the playlist with a friend ?
