Family Sharing for Keep It
Until iOS 14 and macOS Big Sur, Family Sharing was not possible for in-app purchases or subscriptions sold through the App Store or Mac App Store.
It is now possible for developers to turn this on for both subscriptions and in-app purchases, so I have done that for Keep It on Mac and iOS. And I may have been the first, as the notification about Keep It made news.
This will be a boon especially for those who want to use Keep It’s iCloud sharing feature, which allows you to share folders or individual items with other iCloud users, which in a lot of cases may well include family members.
