[2021] New skins

Does anyone know how to get the new skins? It's April 6th, so they should have been released, no?

I'm logged in at Amazon Prime, I'm logged in on Ubisoft Connect, my accounts are connected (as well as Twitch and Youtube), but I still don't see a download or redeem button in neither of them...

Ubisoft Connect doesn't mention the pack at all, and the Anno 1800 page on Prime Gaming just shows a clickable picture of a train, a ship and an airship with gold details, but nothing happens when you click it.
