When you’re in the Survey Analyze tab, the filters you set on the first two tabs DO NOT remain sticky when you get to Text Analytics. This can be very easy to miss, and be very misleading when working on any sort of survey analysis or results synthesis.

The response I got from support was exactly what I thought it would be: the objects underneath are different. This is an unacceptable response to indicate that it is expected behaviour, considering the Survey Text Analytics object has a lookup to Survey Participant object (which is the basis for the Survey Statistics and Response Report). It should be much easier.
