A contributor complains it is not possible to remove from the automatic renewal option using a link in "You can cancel the auto-renewal option by visiting this web page." sentence. I've checked and indeed, the link redirects to http://%22%22/
Link token {$cancelSubscriptionUrl}
has been found in Contributions - Receipt (on-line) message template.
Underneath link ("You can update billing details for this automatically renewed membership by visiting ...") works fine.
Should this "$cancelSubscriptionUrl" be activates / set up somewhere in CiviCRM admin area? Or the link is being sanitized somehow? Wrong / non-existing token maybe? There is not much about $cancelSubscriptionUrl in the civicrm codebase, a few mentions found in email templates only.
WordPress 5.8 and CiviCRM 5.39.0
