We haven’t had to call tech support yet. The COW is our first point of reference when we have troubles.
AXIO and PPRO aren’t perfect but I look at the package as first release (even though PPRO is supposed to be legacy software). Therefore we expect growing pains and are not surprised when we encountered things that are, shall we say, counter-intuitive.
If Ron L’s confidence in the Adobe developers is even half true, we should be able to look forward to a highly functional toolset before too long (fingers crossed).
