HTTP 404 errors when accessing Purview portal (new and old)

Hi all,

I have the "contributor" role in a subscription, and I created a new purview account.

However, when I try accessing the Purview portal (both new and old) there are many missing buttons/functionality. I see there are several errors like the following one:

{
  "error": {
    "code": "ResourceNotFound",
    "message": "Authorization error:[ResourceNotFound:Response content: {\"Message\":\"The Gls FFO Tenant Region was not found for the given tenant: .............\"}, full response: StatusCode: 404, ReasonPhrase: Not Found, Version: 1.1, Content: System.Net.Http.HttpConnectionResponseContent, Headers:\n{\n  Cache-Control: no-cache\n  Pragma: no-cache\n  Server: Microsoft-HTTPAPI/2.0\n  X-BEServer: ......\n  X-NanoProxy: 1\n  X-AspNet-Version: 4.0.30319\n  Request-Id: ......\n  Restrict-Access-Confirm: 1\n  X-BEPartition: .....\n  X-CalculatedBETarget: ..........OUTLOOK.COM\n  X-BackEndHttpStatus: 404\n  X-BeSku: WCS7\n  X-End2EndLatencyMs: 76\n  x-ms-appId: .....\n  X-Proxy-BackendServerStatus: 404\n  X-Proxy-RoutingCorrectness: 1\n  X-FEServer: .....\n  X-FirstHopCafeEFZ: PHX\n  Alt-Svc: h3=\":443\"; ma=2592000\n  Alt-Svc: h3-29=\":443\"; ma=2592000\n  Strict-Transport-Security: max-age=31536000; includeSubDomains\n  MS-CV: ......1\n  Date: Mon, 17 Jun 2024 16:24:25 GMT\n  Content-Length: 112\n  Content-Type: application/json; charset=utf-8\n  Expires: -1\n}]"
  }
}

These 404 errors are returned when the UI makes requests like account?api-version=2023-10-01-preview, /accounts/features, /datagovernance/quality/business-domains/%7B%7BbusinessDomain%7D%7D/report, /catalog/api/atlas/v2/types/typedefs, etc.

The same 404 response is return for a request to /api/gateway/actions/collections/me with a list of roles in the request body such as ["Microsoft.Purview/accounts/data/read","Microsoft.Purview/accounts/data/write","Microsoft.Purview/accounts/source/read",.......

I have the contributor role for the whole subscription and I am the one that created the purview account.

Am I missing any privileges?
