Instead of displaying each individual reviewer's name and their score, you might want to just display the summary of the total score from all reviewers.
To do this, simply add the following CSS to the custom CSS section in Monto Reviews > Customize tab: https://www.monto.io/reviews/customize
monto-review-list, monto-review-sort-dropdown {
display:none !important;
}
Then click save and it will be hidden on your live site!
