1Why is app downloading file from iCloud?
Using iCloud Drive is convenient because it automatically syncs your files across all Apple devices, so you can access them easily from your iPhone, iPad, or Mac. Download screen should disappear.
If it doesn't:
• Connect to Wi-Fi or allow iCloud Drive sync through mobile data
• Check your iCloud Drive JustChords folder using the Files app and download the library.json file
• Check if iCloud Drive synchronization is working. If not, use Google to find articles on how to repair it

You can also turn off iCloud Drive for JustChords in the Settings app.
2How to "Keep Downloaded" on iOS18
The File app in the new iOS 18, macOS Seqouia, and iPadOS 18 has a new Keep Downloaded feature that lets you permanently save all your important files for offline access. Open the Files app, locate JustChords folder on iCloud Drive, long-press a file or folder you want to download permanently, and choose the Keep Downloaded option.
3App stuck on "Discovering" screen
The "Discovering" screen is displayed when iCloud is enabled, and the application checks the status of the data file (library.json). This screen should disappear once the application confirms that the data file exists and is up to date. So far only 1 user has reported freezing on this screen. If this happens to you, please contact marek@justchords.app
