which is............ PFE ATC taking Tea breaks!!!
If I follow a flight plan "exactly" and do nothing else all is well. However, if I introduce anything different like requesting different altitudes, or "say again" or "ACARS"(new version) thereafter I am completely abandoned by ATC. It has happened on half a dozen flights so far. It seems the new release has a propensity to forget to step descend from time to time especially if it also has had a a little spanner thrown in the works!
