Please say more words than "the spin issue" or "the edge issue".
There's so much stuff that those could cover, the more specific the feedback the more possible it is to make improvements.
I can't say I've had issues with edges but for me, "the spin issue" is the AI's general proficiency at playing spin.
I would say it is something that has been encountered by multiple users with a variety of settings and set ups, based on my own experiences plus posts and descriptions on here.
Basically, the AI struggles to bat against user spinners. This usually stems from close catches on the leg side. I've experienced it most with a right handed off spinner to right handers, so the ball is mostly spinning towards leg.
The AI, with a fair degree of frequency, will play leg side shots with the spin that then bounce off their own pads, looping up easy catches to close fielders. This seems to increase in more spin friendly conditions. It's not uncommon to see a spinner take a wicket for 2 or 3 runs at a time.
There's also the "into the boot" defensive shot, where the AI batter does the forward prod, but instead of the ball going into the ground, it's hit the top of the boot and loops up for a catch.
This seems something that should be freakishly rare, but I've seen it more than a few times and I know other users have to.
I'm typing on my phone so it's hard to give a ton of detail on this one, but happy to offer more help and some gameplay examples if they'd be of use.
As
@GuyIncognito suggests, the best counter to it at the moment is to really turn the physics sliders down to nullify spin in general, or remove all close catchers to stem the tumble of wickets. Neither is a terribly realistic solution tho.
