New Form Builder Rules - Where is the bug list?

The rules in the new form builder are utterly unpredictable and loaded with bugs, as others have noted.  At this point, it is largely unusable unless you don't have form rules.  

Where do I go to find out what bugs are already reported before I start putting in support cases?  I don't want to waste my or QB supports time with things already reported.  I have already wasted hours on these forms.
