I have a site that displays manual excerpts on the blog post page: https://teralynnchilds.com/blog. I added a custom read more link using the snippet found here: https://wpmayor.com/add-read-link-manual-excerpts/
The RSS feed (https://teralynnchilds.com/feed) includes the manual excerpt, the custom read more link, AND a default read more link of "keep reading TITLE at SITE". I am trying to remove that default read more link from the feed but cannot find the source anywhere.
How do I fix it some my feed only includes the manual excerpt and the custom read more link?
