A. 1. Update the App: Ensure that you are using the latest version of FET. Go to the App Store, search for FET, and check if an update is available. If so, download and install it.
2. Clear Cache: Go to your iPhone Settings > General > iPhone Storage. Find FET in the list and tap on it. If there’s an option to 'Offload App', do that to clear cache without losing data. Reinstall the app afterward.
B. 3. Restart Your Device: Sometimes, simply restarting your iPhone can resolve app crashes. Hold down the power button and slide to power off. Wait a few seconds, then turn it back on.
