Is daily puzzle rated

Hello,
When practicing on the app, I always begin with the daily puzzle because it's convenient. However, I noticed that sometimes it impacts my puzzle rating and sometimes not. Is there any reason for this?
Thanks.

I think it does. I once did a puzzle on the phone and I lost 30 rating. The daily puzzle rating is usually around 1500.

Yrah well me too but also sometimes it is not rated so I don't know.

Also it happened that I did several times the daily puzzle and each time it affected my rating (which is not supposed to happen with normal puzzles).
