Iphone ringtone

I purchased a ringtone through the tone store but it isn't showing up in my list of ringtones. I saw online while browsing for a solution that you should be able to just tap the purchased ringtone in the tone store and a menu should pop up with the option to make it the default ringtone- however tapping the purchased ringtone does not pull up a menu or anything for that matter.

There is just a button that says play which when pressed just opens apple music and plays the song/ringtone. I can't find an option to set it as my ringtone and it's driving me crazy.

I was worried that perhaps I purchased it as a song rather than a ringtone but again- I bought it in the tone store amongst other ringtones so why would it be in there if I couldn't use it as a ringtone right? Tried purchasing ringtone again but same thing happened so have just wasted money downloading 2 ringtones which I can't set to default as set to my ringtone.

Any help would be greatly appreciated!!
