Feed Invalid in Bloglovin and Feedly

Hi, I updated everything to the latest version, so back version is not an issue. I am trying to allow people to follow my blog in both bloglovin and feedly, however neither of them can find my feed. Bloglovin feed test says there are some issues with the feed. I have no custom code.

“Recommendations

This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.

line 53, column 0: content:encoded should not contain srcset attribute (27 occurrences) [help]

<content:encoded><![CDATA[<p><img class=”alignnone wp-image-176 size-lar …

line 53, column 0: content:encoded should not contain sizes attribute (27 occurrences) [help]

<content:encoded><![CDATA[<p><img class=”alignnone wp-image-176 size-lar …”

If I go to https://www.scrapbookwithlynda.com/feed I do see the correct feed. Do you know why bloglovin and feedly can’t find my blog? I tried a variety of ways to enter it including https://www.scrapbookwithlynda.com, https://www.scrapbookwithlynda.com/feed/, https://www.scrapbookwithlynda.com/blog/ and https://www.scrapbookwithlynda.com

Help please.
