As far as I can tell, only a few individuals from PTC Support sometimes respond to questions. Without more active contributions from the product experts, there are lots of questions that are left unanswered or partially answered. We, clients, are left to support each other as best as we can by volunteering our time. I do contribute answers when I can, but I have never received a single answer to my own questions posted here. As a result, I end up contacting Support directly, but this is not helping our community as a whole.
I think more proactive involvement from PTC is needed here.
