Hello!
A problem I have since the release as VATSIM controller issuing enroute clearances via PDC/DCL (Hoppie): The pilots confirm them in your aircraft with "WILCO". This doesn't lead to a change from status SENT to status DONE in our controller system. Instead it is handled like a free text message by the Topsky plugin. The A300 is the only aircraft I often control having this issue. Please fix it to confirm with the correct message/format.
Best regards – Fabian
