Changed Pipedrive Environment doesn't fit documentation

[dsp76]

Hi there,
marketplace manager is now developer hub as far as I understand. Looks also like its started with Pipedrive sandbox and needs to transferred to live as a next step. However, when trying to re-authorize with the live installation I get authorization errors:

Client error: GET https://XYZ.pipedrive.com/v1/personFields resulted in a 401 Unauthorized response: {"success":false,"error":"Invalid token: access token is invalid","errorCode":401,"error_info":"Please check developers. (truncated...)

The Pipedrive App credentials stayed the same. Could it be a problem with refreshing the token now with the live installation?
