I'm not sure why you wouldn't want to update your Poly to get the latest bug fixes, enhancements and allow it to work with the app. The first updates are essential but later on you will be able to choose via the app whether and when you want to update.
If updating really is a problem for you then I will investigate blocking individual Poly's from the server so they can't update. Just let me know.
That's fine like it is. My habit has always been hold back on updates until I see the net effect on other users, and then decide to go though with it or not. If I can opt out in the future via the app, that's fine. I just like to have options. No need to block my poly.
