I have been having the same problem over the past few weeks, noted particularly when I track my aircraft, N5090C. If one were to look, for example, at my flight of 7/16 that was VFR, no flight plan, but flight following from KPVC (on Cape Cod) to KCDW (Caldwell NJ), one would see a bizarre flight path and an estimated time from BDL to CDW of over two hours, even though the entire flight from the Cape was 1.4. The flight track is bizarre.
Until recently, once I got flight following, as was the case here with Cape Approach, my flight path was accurately described on FlightAware. Now it is hit and miss, and although I always get flight following on my weekly round trip, Flight Aware is only picking up the returns to KCDW, and then not at all accurately, and it entirely missing the the northeast flights from KCDW to KPVC.
ALSO, the notifications have stopped completely.
So, something has changed drastically, and not for the better.
Any clues why?
