You’re not alone on this one mate I have the exact same experience. I really enjoy playing when everything runs smooth. But as soon as you win 2 or 3 back to back out of the blue mechanics stop working or the game gets really slow almost like someone flipped a switch and this go’s on either for the rest of the day which makes you stop playing to came back and find it working just fine for 2 or 3 games and then back again. Really odd.
Hope they can have a look at this. It’s just really weird it happens to so many players in the exact same pattern.
