A. 1. Restart your iPhone: Hold down the power button until you see the 'slide to power off' option. Slide to turn off, then turn it back on after a few seconds. This can clear temporary glitches that may cause the app to crash.
2. Update the app: Go to the App Store, tap on your profile icon at the top right, scroll down to see if Brass has an update available. If so, tap 'Update' to install the latest version, which may contain bug fixes.
3. Clear app cache: Go to Settings > General > iPhone Storage, find Brass, and tap on it. If there's an option to 'Offload App', do that to clear cache without losing data. Then reinstall the app from the App Store.
B. 4. Reinstall the app: Delete Brass from your iPhone by pressing and holding the app icon until it wiggles, then tap the 'X'. Reinstall it from the App Store to ensure you have a fresh version.
