Why can't I play pokemon TCG anymore?

I am trying not to take the win-loss ratio seriously in this game, but from what I can tell there is nothing else to take seriously. Almost every game ends in a bug, forcing me to quit the app and restart the game.  Even when I have a stable connection, I cannot play for no reason so the timer runs out and I lose. Cards will get stuck in the floating position so I cannot use their abilities, some of which are crucial to your deck's playstyle. I have random times that "the opponent is choosing a card" or some variation and that goes on for 10+ min. Why did you have to scrap an old game when this one doesn't work? Playing on your phone is impossible as your phone heats up too quickly and so the game crashes (meaning you lose obviously).  I can't even play expanded against my friends.  Lastly, I have a notification that reminds me every day that since March 30th you are unable to play cards with a D, not for balance changes or anything, but just to make you buy identical cards so the developers make more money.  

I would love to spend more money on the game, if it worked. I would love to level up, if I could play, I would love to enjoy pokemon in the future as I have in the past, but this game has made it so that physical cards are once again the only way to play our beloved card game.
