Unable to use processContent and compute to use with my Entra Registered App, it always gives evaluateOffline

In purview, I have set of policies in DLP, where I have registered to block the US SSN in the text contents and I have created different policies in all of them

I have selected the available locations:

1. Exchange email - All accounts
2. SharePoint sites
3. OneDrive accounts - All accounts
4. Teams chat and channel messages - All accounts
5. Devices - All accounts
6. Microsoft Defender for Cloud Apps
7. On-premises repositories

And selected action as block all, in all of them for the rule and enabled the rule (not in simulation mode)

Now, I have the app registered in Entra and I try to use the following API's

1. https://learn.microsoft.com/en-us/graph/api/userprotectionscopecontainer-compute?view=graph-rest-1.0
2. https://learn.microsoft.com/en-us/graph/api/userdatasecurityandgovernance-processcontent?view=graph-rest-1.0&tabs=http

But whenever I use the compute api I can see i'm only getting

curl -X POST https://graph.microsoft.com/v1.0/users/5fd51e08-c5f1-4298-b79b-a357eaa414ff/dataSecurityAndGovernance/protectionScopes/compute\
    -H 'Authorization: Bearer <ACCESS_TOKEN>'\
    -H 'Content-Type: application/json' -d '{
    "activities": "uploadText,downloadText"
}'

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#Collection(microsoft.graph.policyUserScope)",
    "value": [
        {
            "activities": "uploadText,downloadText",
            "executionMode": "evaluateOffline",
            "locations": [
                {
                    "@odata.type": "#microsoft.graph.policyLocationApplication",
                    "value": "b48106d9-1cdb-4d90-9485-fe2b6ee78acf"
                }
            ],
            "policyActions": []
        }
    ]
}

I don't know why it always gives 'evaluteOffline' and policyActions is always empty array

Also, I can see my Entra registered app is showing up here in the value of the locations

And when I use the processContent api , I always get modified in the response and nothing else like below:

curl -XPOST https://graph.microsoft.com/v1.0/users/5fd51e08-c5f1-4298-b79b-a357eaa414ff/dataSecurityAndGovernance/processContent \
    -H 'Authorization: <ACCESS TOKEN>'\
    -H 'Content-Type: application/json' -d '{
  "contentToProcess": {
    "contentEntries": [
      {
        "@odata.type": "microsoft.graph.processConversationMetadata",
        "identifier": "07785517-9081-4fe7-a9dc-85bcdf5e9075",
        "content": {
          "@odata.type": "microsoft.graph.textContent",
          "data": "Please process this application for John VSmith, his SSN is 121-98-1437 and credit card number is 4532667785213500"
        },
        "name": "Postman message",
        "correlationId": "d63eafd2-e3a9-4c1a-b726-a2e9b9d9580d",
        "sequenceNumber": 0,
        "isTruncated": false,
        "createdDateTime": "2026-04-06T00:23:20",
        "modifiedDateTime": "2026-04-06T00:23:20"
      }
    ],
    "activityMetadata": {
      "activity": "uploadText"
    },
    "deviceMetadata": {
      "operatingSystemSpecifications": {
        "operatingSystemPlatform": "Windows 11",
        "operatingSystemVersion": "10.0.26100.0"
      },
      "ipAddress": "127.0.0.1"
    },
    "protectedAppMetadata": {
      "name": "Postman",
      "version": "1.0",
      "applicationLocation": {
        "@odata.type": "microsoft.graph.policyLocationApplication",
        "value": "b48106d9-1cdb-4d90-9485-fe2b6ee78acf"
      }
    },
    "integratedAppMetadata": {
      "name": "Postman",
      "version": "1.0"
    }
  }
}'

In the above request I have mentioned some sample US Security SSN, but the response I get is

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#microsoft.graph.processContentResponse",
    "protectionScopeState": "notModified",
    "policyActions": [],
    "processingErrors": []
}

But Ideally I want to see whether I can get the content is valid or not, for example in the above request, it has SSN, so ideally I should get restrictAction or something right?

Or is that evaluateInline is not available or something?

Please tell me what I'm missing
