Seems a bit excessive that only one user account (the Manager user) can delink a customer's GoCardless DD mandate reference, especially when the linking is so clunky and easy to make a mistake. Having to go and request that the Manager user delinks these customer mandates is a waste of their time, and it would be useful I believe if an Administrator user type with full access could be able to do this.
Very annoying now that users have indiviaul accounts and the 'MANAGER' doesn't have two factor login
