What's taking so long to get the new cards?

Commander Legends: Battle for Baldur's Gate has been out for quite a while now, and MTGVault still doesn't have the cards in its database, while almost every other deckbuilding site did weeks ago.

I really like this site and use it all of the time (I have over 3000 decks...), but it seems like it takes so long for this place to catch up... what's going on?
