Sadly, as I'm told time and time again, it will still convert from Oasis to UCP in a few weeks. That means Chat had to go (but you got Discord and other methods of communication). If you got emojis made for your Wiki, they may still exist post-UCP conversion. CSS will also remain (but with several modernizations and improved performance).

Fandom Staff (and the advertisers, somehow) care and are listening to you. They paused the conversion for the retaining 62% of the wikis.
