User blog comment:MisterWoodhouse/The first Unified Community Platform release is now live for NEW wikis/@comment-168424-20200313172542

So it appears that starter.fandom.com was also changed for the new UCP and is basically screwed up (i.e. https://starter.fandom.com/wiki/Special:SpecialPages). Is the old one archived somewhere?

I just created a new UCP wiki and there lots of missing pieces. I'm disappointed. Feels very rushed.
