This subsection configures the generation of link previews for links sent through the app. Available since version 3.52.

Parameter Description
Allow link preview generation If the checkbox is cleared, no preview will be loaded for any links sent through the application.
Blacklisted IP addresses This configures IP ranges of hosts for which link previews will not be loaded.
Whitelisted domains Link previews will only be generated for domains specified here.
⚠️ When the white list is enabled, the black list does not work, because the white list takes priority.
