The Experimental Features is a test not visible to all. I for example don't have it either, so don't worry about that. :)
Make sure you're logged in to the right account. Spotify receipt shows your username, make sure you're logged in with that one.
I also suggest reading this article for more information on how to find accounts.
Do you see Premium features such as downloading playlists and enabling high quality streaming? If not, you might be logged in to a Free account, not one with Premium. Is everything else (your playlists and saved songs) looking right to you?
Let me know :)

Yes I’m in the right account. Everything else looks ok. Playlists are all as they should be. Only daily mixes aren’t there. I did see the experimental option last night using the desktop application on my home PC.
