Feed not working

Hi all.

I set up the subscription through Specific Feeds as Ultimate has set up, but no new emails are going out to my subscribers. I am super new to feeds and am hoping someone might be able to help with this as I already have a few subscribers. The address is https://www.thelitmolife.com.

Thank you in advance!
