Someone has typed a credit card number into the customer visible notes field on a service request task. We'd like to remove it, either by amending or deleting the note.
I've tried following the instructions in this community post:
https://community.servicenow.com/community?id=community_question&sys_id=beb58321db1cdbc01dcaf3231f96...
But it doesn't work. I do everything, but when I go back to the task record, the customer visible notes field has not changed. That post is a few years old so may apply to an earlier version. We're running Helsinki.
