Hey Spencer, unfortunately this is fairly common over the past 6 months.
It’s worth messaging support, but generally it’s just a “wait until they fix the service outage” game. Should be up in a few hours.
Until then I would recommend you do not try to add items.
The webflow system is a huge assortment of different services and a few of them are relatively fragile. Three I see regularly fail are;
- the CMS list items endpoint used internally to populate this screen
- site search. When it’s down, users will simply see no site search results on your site
- embedly, which handles e.g. video embeds. When it’s down, you cannot add new items successfully
