    The solution isn't working. I waited a few days for the policy to be applied, but it is still not working.

    My tests were the following:

    1. Created a file with a Confidential label.
    2. Shared it with an external account.
    3. Verified access from the external account.

    Maybe I need to create a new file with the Confidential label and wait a few more days before testing again. What do you think? fvaldez_9​ VasilMichev​
