On my highly unscientific personal tests, I noticed that the device and internet speed are not so important factors (at least not on iOS). Most games run just as well (or badly) no matter how far from the wifi router I'm sitting. From the router to my bed there's about 15 meters and two thick walls in between. I can browse on my phone and play other games without any issues, despite the distance. However, Cookie Run starts loading slowly and dropping the connection if I'm more than 10 meters away from the router. I move closer, and it works fine.

I pay for 100/100 Mbit internet, which I can easily reach on my computer. My measured speeds on my iPhone 5S were about 25 Mbit down and up, and mom's iPad about 35-40 where I'm playing, which should be more than enough for Cookie Run. So I can only conclude it's an issue with the game.
