The problem comes from sharing Apple ID.
Apple ID was never designed to be shared.
Just one. Use the same Apple ID everywhere you sign in to ensure that all your Apple services and devices work together seamlessly and you can access your personal content from all your devices.
Your Apple ID should not be shared with anyone else. It provides access to personal information including contacts, photos, device backups, and more. Sharing your Apple ID with someone else means you are giving them access to all your personal content and may lead to confusion over who actually owns the account.
To share iTunes & App Store purchases, photos, a calendar, and more with someone else, try Family Sharing, iCloud Photo Sharing, or other easy-to-use sharing features.
