The new german-eudi-wallet common trusted entity trusts the PID providers of the German EUDI Wallet (d-you) production environment, from the trust list published at trustlists.eudihub.de. Link it as a trusted issuer on a presentation template to accept only the production PID.
german-eudi-wallet-sandbox now uses the sandbox trust lists published at trustlists-sandbox.eudihub.de. They list the same PID and wallet providers as before, so templates that link it need no changes. See the d-you guide.
