How do I set a single song to repeat?

When the song is playing tap on the repeat button until you see "1". Or create a playlist that only has that song and repeat the playlist.

When I click the repeat button I can only toggle twice. There comes no '1'. Im talking about the preview app though.
 
Not certain about preview app, I can do it on the MixRadio app. Just tap twice and it will repeat with a little "1" in the icon.
 
Im obviously talking about the new music app Groove.
You can tap all you want but it switches only between normal playback and repeat of the album or something. It has only two modes.
This is freaking hilarious.
This music app has almost no functionally at all. They act like it is super science to add all these tiny features. A billion music players like winamp and other ancient players had a billion features.
I don't get it why progress is so hard and endlessly slow with these apps.

I am using groove music and the single song repeat works for me. I can toggle 3 times.
 
Unfortunately even I don't see option to set a single song to repeat. Such a small thing but the most basic thing Windows has missed it. I guess they should release it in their next patch asap.
 
Will most of your just stop with "ugh, it doesn't have even this most basic thing".

*There is song repeat* in both Xbox Music and Groove on both phone and desktop.
