Apple Music Family account not linking to the Amazon Alexa app

The solution didn't seem to be documented anywhere so here goes...

There's an age limit on the Apple music accounts which can be linked to an Alexa account.

I think the limit was 13 years of age. The only way round it is to have older children.

If you have incorrectly created your children's Apple accounts with dates which show they're younger than 13, it isn't possible to change the date of birth. A new account can be created with their correct date of birth showing they're 13 years or older.

If you're keen to stick with the same email address/account name for your child, their existing Apple account can be deleted and a new account can be created with the same details but a corrected date of birth. After deleting the account, it takes several days for Apple to complete the deletion process before another account can be created. This will lose history, emails, subscriptions etc.

This article says the same account name can't be re-used: How to delete your Apple ID account – Apple Support (UK). That wasn't my experience and I was able to re-create with the same account name. I suspect that was because I was using a third-party email address, (outlook.com) not an icloud.com address but be aware that if you delete your child's account you may not be able to re-create an account with the same name.

Hope this is of use to anyone pulling their hair out like I was.

Responses like this kill forums. It doesn't relate to my fairly detailed query which makes clear I already know how to link my account but get an error message which isn't mentioned in the article reference.
