I am thinking about enabling them for a similar purpose although my style will be different. e.g. when a reviewer mentions not being able to reorder items I might send everyone a push to a tutorial explaining how to reorder lists. Afterall if one person is struggling maybe others are (I also look at my usability again after reviews like that).

I wouldn't call out specific reviews or even mention the trigger in any push messages although I have put responses to many reviews on my website.
