A. 1. Force close the app: Double-tap the home button (or swipe up from the bottom on newer iPhones) to view all open apps. Swipe up on the Fit the Fat 2 app to close it. Then, reopen the app to see if it loads properly.
2. Clear the app cache: Go to Settings > General > iPhone Storage. Find Fit the Fat 2, tap on it, and select 'Offload App'. This will free up storage without deleting your data. Reinstall the app afterward to see if it resolves the loading issue.
B. 3. Restart your iPhone: Sometimes, a simple restart can resolve loading issues. Press and hold the power button until you see the slider, then slide to power off. Turn it back on after a few seconds.
