I’m having issues with the post snippets in the autocomplete results – at least for me they are completely irrelevant. It seems to pick random things off the page. It seems like there should be an option in the plugin to turn this off. (I tried adding some code to my stylesheet to do this but it did not work.)
Better yet, why not have an option to use the OG:description? For those of us that use Yoast these are already available and optimized.
