Yes, since last update, when they added new internal things to improve the game, it seems the game is requesting more memory usage than usual, so for not maxed CPU or RAM devices is not working well, specially on Android and PC emulators. I have an iPhone 6S and is working well. When I only use 1 instance in BlueStacks works well, but when I switch to another instance several times then crashes constantly. If I use 2 BlueStacks instances then works very bad, I cannot use them at same time, I need use one and when is logout use the other one. I have a good PC with 16 GB RAM and Intel i-5 processor, before the update was working well with 2 or 3 instances at same time, now crashes constantly if I use 2 at same time, like with operations syncronization.
The forums about bugs and technical problems are full of these problems, better write there to insist with it and force to the developers to find a solution as soon as possible:
