With the update a few versions ago, plan members are no longer able to update plan-specific custom fields. For example, there are 10 different plans on our site and a user can be a member of more than one account. Membership plans all have their own private fields. In one membership plan, we receive the member's IBAN information in another membership plan and a different information of the member with a special field. Until a few updates ago, our members could update this information from their profiles, but now no information is displayed except basic information.
