Query Masking - Does it work?

Hello,

Has anyone tried query masking and made it work?

For my testing,

1. I have EX_EE_PYMNT_DTL.BANK_ACCOUNT_NUM is set as a PI and Sensitive Information.
2. Query Masking is enabled
3. Set one role as Authorized for EX_EE_PYMNT_DTL.BANK_ACCOUNT_NUM
4. Ran Query Data Masking Sync
5. Created query on EX_EE_PYMNT_DTL where BANK_ACCOUNT_NUM <> ' '
6. Query result shows BANK_ACCOUNT_NUM not masked
7. Set role from #3 as Unauthorized for EX_EE_PYMNT_DTL.BANK_ACCOUNT_NUM
8. Ran Query Data Masking Sync
9. Ran same query as in #5
10. Query result shows BANK_ACCOUNT_NUM not masked
