Is there a limit of Upsells I can offer on a product?
By default, only three products appear in the upsell modal on the storefront. If you would like to display more than three products, enable the "Show all offered products" setting within Bold Upsell. This adds arrows to each side of the Upsell modal so your customers can scroll through your offers. You can enable this setting in Upsell under Settings > Upsell Settings.
