Fetch Account Types API currently returns the account type details including any accounts (with any status) associated with the account type.

The API response will now exclude any closed accounts and will be live in stax-au1, stax-us1 and stax-eu1 on Wednesday 1st February at 0200 UTC (Tuesday 2nd February at 1300 AEST).

If you have any concerns about the change, please raise a support case.
