Cannot delete developer used in DEVELOPER_HAS_RATE_PLAN

[#1]

Is there a way to delete a user who has been placed on a Monetized product? Trying to delete the developer results in a "Cannot delete developer used in DEVELOPER_HAS_RATE_PLAN".

I ended their rate plan so they would not have any active plans. It is still throwing the same error though.

Is there an additional step I need to take, or can I not delete these users?

Thanks.
