Your definition of "upgrade" and mine are different!
Every time you upgrade this app it seems to have new problems. Ever since it became "Stream" it randomly quits: I am watching at home, on my home wifi and for no reason it just stops and then closes. To me, that is not an upgrade! Also, for out-of-home use, the old TO GO version was better than the way it is all combined now: much easier to find things and to use.
