A. Ensure that your internet connection is stable. Try switching from Wi-Fi to mobile data or vice versa to see if the loading time improves. Additionally, close any other apps running in the background to free up resources.
B. Clear the app's cache to improve performance. Go to 'Settings' > 'General' > 'iPhone Storage', find Wanna Kicks, and select 'Offload App'. This will remove the app but keep its documents and data. Reinstall the app to see if it loads faster.
