The cause is almost always in Change details: the button is switched off, or the date, time or location is missing. Go through the points below.
In your dashboard, open the menu (three dots) next to the invitation and choose Change details. Tick Enable calendar and Enable navigation, then click Save settings.
Without a time, Add to calendar puts the event in your guests’ calendars at 00:00. Fill in the start time under Time.
Directions uses whatever is in Location. If that field is empty or only says something like “at our place”, the map app can’t find it. Type the address and pick a suggestion from the list that appears.
If you open the link from Instagram or Facebook, for example, it opens in that app’s built-in browser, where saving to a calendar sometimes fails. Open the link in your regular browser.
More about these buttons: Turn on the Add to calendar button and Turn on the Directions button.
