A. 1. Ensure your iPhone is running the latest version of iOS. Go to Settings > General > Software Update and install any available updates. 2. Delete the RoadReady app and reinstall it. Press and hold the app icon until it wiggles, tap the 'X' to delete, then go to the App Store to download it again. 3. Clear the app's cache by going to Settings > General > iPhone Storage, find RoadReady, and select 'Offload App'. This will free up storage without deleting your data.

B. 4. Restart your iPhone by holding the power button and sliding to power off. This can help clear temporary glitches.
