I'm on the T Mobile variant, and since I upgraded to marshmallow last week, I have had Samsung Pay crash and become wiped from my phone three times. This is after having zero issues with it since I got the phone last fall. I have tried every possible solution, including uninstalling and reinstalling. Clearing cashe and even a factory reset. All to no avail. I spoke to reps from Samsung, and they seem dumbfounded as to a solution. They are telling me they have to escalate the issue in there tech department. Has anyone else had this type of issue since the update?
