I am Japanese and am not good at English.
It may be difficult to read, but please understand.
In the sandbox environment, it is necessary to test "Approval and purchase request (Ask-To-Buy)" of in-app purchase.
Therefore, "Family sharing" was set.
However, I was charged at the child terminal, but the approval notification did not reach the parent terminal.
Tested with the following configurations.
■Family sharing settings
A 16-year-old account is added as a child to the parent account.
"Approval and purchase request (Ask-To-Buy)" is set to "On".
■Parent terminal
・iCloud
Sign in to sandbox environment with parent account
・iTunes and AppStore
Sign in with a regular account (not a sandbox account) with payment information registered (because credit card information could not be registered with the tester account)
■Child terminal
・iCloud
Sign in to the sandbox environment with your child account
・iTunes and AppStore
Sign in with the same account as iCloud
How do I set up notifications on the parent device?
Please help me.
