Download and install the latest version of the plugin from Forum/App Market. If you are already using the latest version of the plugin, leave a comment to the maintainer or open a case with Appian Support.

This can affect all versions of Appian. It is currently affecting Appian 17.4 with ADM versions less than 2.4.2.
