This is an Online Event

Why doesn’t the content in the “This is an online event” show on the web event page as a button someplace?

Example:
https://mtsac.lwcal.com/world-languages/event/759765-japanese-grammar-game-night

Online events were added in LiveWhale 1.7.1, and if you had previously customized your event details component (or event component, for list view) there are a few small theming steps to get the online event pieces showing up on the front-end:

These changes are included in the core theme with 1.7.1, but you’ve probably already customized at least one of the affected components. Follow the steps below to incorporate the newest online events code into those components.

So for instance, you can edit _ingredients/themes/global/components/calendar/lw_cal_event_detail.html to include the recommended code from the docs to get that button showing up:

{[ if (obj.online_url) { ]}       
        <a class="lw_join_online" href="{{ obj.online_url }}">
                {[ if (obj.online_button_label) { ]}
                        {{ online_button_label }}
                {[ } else { ]}
                        Join Event
                {[ } ]}
        </a>
{[ } ]}


{[ if (obj.online_instructions) { ]}
        <div id="lw_cal_online_instructions">
                {{ online_instructions }}
        </div>
{[ } ]}
