Fixes lag/performance issues on iOS 15.4+
Please update your device to iOS 15.4 when it is released to fix performance problems related to WebKit present in iOS 15.0 - iOS 15.3.
Technical details:
Pocket City uses WebGL to render graphics. iOS 15.0 to iOS 15.3 contains a bug in WebKit causing a worse performance in WebGL. Pocket City instead used a canvas renderer for iOS 15.0 to iOS 15.3, but the performance was still sub-par. iOS 15.4 fixes the WebKit performance bug, and this update reverts Pocket City to use the WebGL renderer again. With this app update and iOS 15.4, Pocket City should be back at full performance.
