“Continue Reading” no longer showing up?

I have 3 sites that use Mission News and have been for a few years now.

Typically on the main page, the main image and first couple paragraphs for each article will show, and then the “Continue Reading” link.

However, the “Continue Reading” link disappeared recently. To be honest, I’m not sure exactly when, but I haven’t changed any settings or CSS, so I have to guess/assume it happened with a recent update, either to Mission News or to WordPress/Jetpack.

Does anyone have any insight as to what happened and how to fix it?

Thanks so much!
