My apologies if this was brought up when the change happened (due to real life reasons I had to take a few months away from the game), but why do puzzle tiles now have a delay between activating one and being able to activate another? I love puzzles, but this makes tile puzzles frustrating AF, when I click on a series of tiles to solve and only the first one turns and I'm forced to wait a second between each and every move.

edit: the delay is less than one whole second, but it is very noticeable.
