I am playing Hearthstone on iPhone 7, OS 14.1. Whenever my opponent shuffles their hand into their deck (Plot Twist and Glide), my Hearthstone app crashes. This has been happening since Duels patch, and has happened 100% of the times opponent has resolved Plot Twist or Glide, including when Glide is cast by another spell such as Puzzle Box of Yogg Saron.
Add dead mans hand to that list 
I did not see this topic but I just reported the same issue. Happens every time with plot twist. I am not sure if I ever played against someone who played glide.
Same issue on me, iOS 14.1 and now upgraded 14.2 and still same. DMH not Played on std. But probably that does same.
