A. 1. Check for any available updates for your iPhone's operating system by going to Settings > General > Software Update. Install any updates if available. 2. Clear the app's cache by going to Settings > General > iPhone Storage, finding the Michaels app, and selecting 'Offload App'. This will remove the app but keep its data, allowing you to reinstall it fresh.
B. 1. If the app continues to crash, try resetting your iPhone's settings by going to Settings > General > Reset > Reset All Settings. This will not delete your data but will reset system settings.
