Following the upgrade to 5.3.0, we are finding that the 'Check for Matching Contacts' button, which is in the edit contact screen, is not working. The screen refreshes and reloads the same contact, with no error message.

If you run the default supervised rule from the 'Find and Merge Duplicate Contacts' screen, it picks the duplicate up. But the Check for Matching Contacts function has stopped working. Is this a bug anyone else is seeing?

Thank you!
