In P3Dv5 when parking at a GSX configured parking spot such as KIAH E19 with a marshaller I am unable to use jetway and get a message from GSX that it is waiting for other services to complete. What might those other services be? I've selected a parking spot when downwind, parking at the spot selected, got a message that says very good parking but can't go any further in the flow. What might that be and how can I work around it other than restarting couatl? Thanks.
