I don’t want to be rude but I am not surprised they are not reading your post. Do you know how many people want to have access to Epic engineers like you? Thousands, if not tens of thousands. If they talked to anybody, they wouldnt have time to do their job.
You need to sign up for premium support if you want to enter into a discussion with them. It costs 1,500 USD a year to enter the Enterprise program.
I also did not get an answer at first, but keep trying and eventually they will. This also shows that even the demand for this support is huge…
