As for the other issues, they're either simple QoL issues or obvious server issues. @qilp and @Goondrious are working on it and many of them will have a fix within a day or two.
New game is bugged (look at the chat)
https://www.chess.com/variants/spell-chess/game/53499447
Also there's a sound of reloading after every my move
In the updated new version:
a) there are very annoying points (showing possible moves), impossible to remove,
b) the zombie king is not shown as previously,
c) there is no more specific sound when it's YOUR move.
Guys, why on Earth are you changing something that works well?
In addition: you cannot see who ate what anymore. The eaten pieces are not shown.
I don't like it 
It looks too much like a dead piece and is too confusing
Fourway chess is glitching something awful.
Whenever someone forfeits, until their king is mated the game shows double moves by sever other players.
Fog of War has been broken for the last 48 hours or so. You can now see a highlight (and sometimes the piece) that has been moved and the resultant square. The fog of war variant should only show visible pieces/squares
@PALLASam I have the exact same problem. If you try to tap and slide a piece, it ends up moving other pieces and cancelling a legal move. Yesterday I played this Spell Chess game:

On moves 4 and 5 I tried to move the queen to h5 on the phone, but it was unfair and somehow wanted me to play unusually.
Would you mind telling us why there's an 8-dot image guide in the image??
I don't know. I happened to have power-point on my screen and my computer froze when i tried to close the tab. I at the moment had a duck icon selected. the computer froze and i took a screen shot.
The worst update of variant chess!!!
Description: error of scores and pieces in one of my games and even in analysis
Error 1: zombie chess piece
Like the picture why the piece of blue when giving up turns into a zombie (all pieces)
Error 2: The score displayed quickly on the screen is very strange
My game link: https://www.chess.com/variants/4-player-chess/game/53548407/15/3
Sometimes I take my opponent's king and the quick score display says I got 3 points even though in my real score I got an extra 20 lol
I'm not talking later games and next time because it's likely already fixed
Bosses of Chess.com ruined variants server by adding Spell Chess?
There is a bug in spell chess. When I freeze the black king then use bishop to checkmate, the panel say it checkmate, but the game doesn't end.

Why when I want to make a custom four-player chess position I can only put red pieces?
