Kentico Xperience 13 - BizForm Notification Encoding (CMSBizFormMailEncodeFields)

Hi there,I am having issues with encoding form field entries with Bizforms in Kentico Xperience 13. I am running version 13.0.83, having intentionally implemented the hotfix 13.0.72 to attain the ‘CMSBizFormMailEncodeFields’ configuration key. I have implemented the CMSBizFormMailEncodeFields and set the value to true in appsettings.json for both the live site and administration projects. Unfortunately, the fields in the autoresponder and notification emails are not encoded. Has anyone successfully implemented the CMSBizFormMailEncodeFields configuration key and found it to work? Or have any suggestions on resolving this?Thanks
