Core Prohibition: It is strictly prohibited to log into shared accounts in the [iCloud] section of iPhone settings. Accounts must only be logged into within the [App Store] app store. This is the most critical step to prevent iPhone lockouts and protect personal information security (refer to the login diagram below for guidance).
2. Exit promptly: After downloading the purchased App, immediately log out of the shared Apple ID and switch back to your own account. This will not affect the usage of the installed software and helps prevent login failures due to account maintenance.
3. Auto-refresh Instructions: If you encounter an account lock or password error prompt, please refresh this page later. Our system automatically detects and updates the latest available US region ID every 30 minutes, eliminating the need for manual password reset attempts. Do not bind any personal payment information or purchases to shared IDs.
