Tried many suggestions mentioned here and so far no pay dirt to get store/select apps functioning again, its getting a tad sickening to spend hours or days after an update looking for a resolves to these induced problems. Have 6 devices now running the Anniversary Update w/five needing or that needed attention (issues being very broad and different), there is absolutely no joy now when a W10 update ensues because it is pretty much a guarantee it won't be error free, so much for being "pain free" and thanks MS... NOT! :angry:
