Samsung Galaxy S3 Tablet, the S-Pen is no longer functional with the game. You can do some things - like hold on a card for information, but you cannot move cards around. So, yes, confirming, and relying on my finger, which is kind of a drag. So used to the pen.
Additionally, the Squelch key is no longer working (and I squelch every player before a match, so this is an annoyance).
Also running through my 10 decks, it used to put a glow-border around my last played deck (so I could pick up where I left off if I have to log off the game) - it no longer does this.
So yeah, a few things. But pen functionality coming back is my #1 request. It’s amazing how good this game operates with the pen, and how much I miss it.
