Have to say deleting the game was the best thing Ive ever done. Went from spending hundreds a month to the rare purchase then to asking myself why i even bother playing free with the constant issues. By the posts i see when i check in here periodically i see the choice was the right move. If you're struggling with why you still play try deleting it and you'll see there isn't much you'll miss. Its clear looking back that Gree won't change, the issues/bugs will remain the same and the grind is never ending.
The game is dying... why bother anymore?
Give it a shot and delete the app.. even if its just for a week. See how it goes.
