I am new and currently trying to learn to play a song on my acoustic guitar. I practice it once a day for about 30 mins and while I have noticed slight improvements most days, for the past two there has been no improvement.

Would you recommend I continue learning the song till it's down or learn something else and come back to it?
I never push it. It rarely leads to something good, and the frustration you can get from trying too hard can lead to serious negative feelings about the subject in general. It is true for any kind of learning. I go and do other things, and get back to it when I feel that it is a good time to try again.

If you have to learn something in very limited time it is another thing of course.
