TLDRThis Issue

Absolutely love the Echo RSS Plugin! Right now I am running it on a staging site to test some things out. The main thing I wanted to test was the TLDRThis integration. I have 1 RSS feed setup, with a maximum of 1 article import to test. I got the free API key. I set everything up like in the demo video. I can see the API requests on the API dashboard. The log has no errors. Yet, it produces an empty blog post. When I turn off the integration, it pull the full article with no problem at all. I have tweaked so many different options to try and get it to work, but with no luck. Please help? Thanks Rich
