Transition page is not working

Hello Team,
I’m using Matomo latest version 4.14.1…
When I’m trying to access transition page it is showing error({“result”:“error”,“message”:“Call to undefined function Piwik\Plugins\Referrers\getReferrerTypeFromShortName()”}).

We need to install user flow plugin ? or any option to fix this issue ?

Anyone knows about it ?

Resolved. Thanks for your so called support.
