A. 1. Update the app: Go to the App Store, tap on your profile icon at the top right, and scroll down to see if JW Library has an update available. If so, tap 'Update'. 2. Clear app cache: Go to Settings > General > iPhone Storage > JW Library. If there's an option to offload the app, do that. This will clear temporary files without deleting your data. Reinstall the app afterward. 3. Restart your iPhone: Hold down the power button and slide to power off. Wait a few seconds, then turn it back on. This can help clear any temporary glitches causing the crashes.

B. 4. Free up storage space: Go to Settings > General > iPhone Storage and check if you have enough free space. If not, delete unnecessary apps or files.
