You might see Fomo as a blocked resource in Google, rest assured this will not effect your Google indexing or page ranks.
Using robots.txt, Fomo requests our pages and files from not being indexed (aka blocked). 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 effect your indexing on any search engine or search results.
