Identify the profile that owns account administration
The official account guide says email changes, password changes and disconnecting devices can be performed only from the principal profile. A secondary profile can be a legitimate viewing environment without holding those management controls. Confirm which profile is active before opening Account Management.
This matters on a shared device where the last viewer selected their own avatar. A familiar account email at sign-in does not mean the principal profile is currently selected. Keep account identity and profile role separate when describing a missing control.
Open the specific security action
From the principal profile, ADN directs users through Manage Account and Security. Email changes begin an email-guided process, while password changes have their own action. Choose the intended one and follow the resulting instructions rather than editing an unrelated display field.
Before changing an address, confirm that the account holder can receive the required messages. Do not create a replacement account simply because a secondary profile does not expose an email control. That would separate the viewing history and paid agreement from the new identity without resolving the original administration question.
Allow for the documented device-disconnection delay
The same guide says disconnecting all devices may take several hours to become effective. Record when the action was requested and which result is being checked. Seeing one device still active immediately afterwards is not, by itself, evidence that the action can never work.
For a persistent issue, use ADN’s official recovery or support route with the account context and timing. Do not send passwords, validation links or one-time codes to another viewer as a workaround. If the aim is removing one unused secondary profile, use the profile-management instructions instead of confusing it with a request to disconnect account access everywhere.
