My wife and I just both uninstalled the app, , force closed all applications, optimized for high performance, redownloaded aand ended up with the same results, both of our phones have a native performance scanner from Samsung which reads 100/100 on both devices. This is definitely a frustration seeing her screen showing the entirety of a cave while my screen is "zoomed in" by default with the only option to zoom in more through the game setting.
