Invoice from Digi-belgium not received via Peppol

Same problem with receiving invoices from Hey Telecom, only via email attachment and not via Peppol

Same here with two suppliers. Only via email and not via Peppol. Even though we have already received invoices from other suppliers via Peppol.

Finally, six days after the email with the invoice attached, I also received the electronic invoice via Peppol :-)
