You might see Fomo as a blocked resource in Google. Rest assured this will not affect your Google indexing or page ranks. There is no action required on our customer's end nor update required to their robot.txt
robots.txt is simply asking Google to not index (aka block) our pages and files. The "Blocked Resource" in your Google Search console is merely a result of our snippet on your website. This snippet is required to allow Fomo to work on your site, but we just don't want Google to index our snippet.
Again, this will not negatively affect your indexing on any search engine or search results.
