 The theming app supports changing the URLs for the mobile apps (Android and iOS) that appear when users access the web interface from mobile devices. By default, these links point to the official Nextcloud apps, but you can set them to branded versions.

+Scopes and existing users
+-------------------------
+
+The ``account_manager.default_property_scope`` config only applies to **new** users.
+Existing users keep their stored scopes.
+
+There is currently no admin-level mechanism to bulk-change scopes for existing
+users. The OCS provisioning API only allows users to change their **own** scopes —
+admins cannot set scopes on behalf of other users.
+
+Users can update their own scopes in **Personal settings** → **Personal info** →
+**Edit your Profile visibility**, or via the API::
+
+  curl -s -u alice:password -X PUT \
+    "https://cloud.example.com/ocs/v2.php/cloud/users/alice" \
+    -H "OCS-APIRequest: true" \
+    -d "key=phoneScope&value=v2-private"
+
+The scope key is the property name with ``Scope`` appended. Available keys:
+
+``displaynameScope``, ``emailScope``, ``phoneScope``, ``addressScope``,
+``websiteScope``, ``twitterScope``, ``blueskyScope``, ``fediverseScope``,
+``organisationScope``, ``roleScope``, ``headlineScope``, ``biographyScope``,
+``birthdateScope``, ``avatarScope``, ``pronounsScope``
+
+Allowed scope values:
+
+- ``v2-private`` — Private
+- ``v2-local`` — Local
+- ``v2-federated`` — Federated
+- ``v2-published`` — Published
+
+.. note::
+   ``displaynameScope`` and ``emailScope`` cannot be set to ``v2-private``.
+   The server enforces a minimum of ``v2-local`` for these properties.

+This page collects configuration changes that can improve the performance of
+your Nextcloud server. Most items only require editing a configuration file or
+installing a package, while a few involve additional services. Start with the
+ones that match your setup and revisit the rest as your instance grows.
