PII is generally pretty broken, particularly for phone number
PII filter is not functioning correctly when ONLY PII is present in the body, e.g. phone number.
Example: 202-555-0156 does not return a PII object, whereas "Test phone number 202-555-0156" does. This makes it pretty unusable when people are, i don't know, exchanging phone numbers when they shouldn't be?
Likewise, something like "aaaa aaaa 203-456-5928" doesn't return it either. Can you either fix this or eliminate any charges for PII calls? This is broken to the point of being unusable and Microsoft shouldn't be charging for this.
