IOS - New app broke sharing to friends and can’t add new friends

[darcilicious]

If you mean “single item sharing” it’s no longer supported:

@PlexInfo

Single Item Sharing: We’ll no longer offer the ability to grant access to single, individual items on a Plex Media Server (such as an individual playlist or single specific movie). Existing individual items will still remain accessible in the new apps. However, you will not be able to do so for new, individual items. You can continue to grant access to libraries on a Plex Media Server to family and close, personal friends.
