Family Plan Admin Problems

Steps:

• Created mailbox.org account, was still in trial
• Created Family Members
• Logged into each family account individually, no ability to change plan to Lite/Light present
• Figured it was because main account was in a trial
• Changed to paid but could not change family members so had to pay Standard x 4 (definitely not what I wanted but I was stuck and hoped for the ability to downgrade/credit value to account)
• Still no ability to admin Family Members, can't set custom domains for family, can't change passwords, can't remove members, can't change plan for members (in main admin or in each individual account).

Have I gone about the order all wrong or have I missed something to enable? Seems like certain features are completely missing to me. Have sent off a Support Request. Any ideas?
