I am unable to change the Samsung Pay Pin #. Followed instructions on another post here. Found the framework, trying to "force stop" this app but I continue to get the message: "if you force stop an app, it may cause errors". I then go to storage and can clear cache. I go to manage storage and do not see an option to delete data. I do see that the Force Stop is grayed out. Does this mean that I was able to force the app to stop? If so, then how do I clear the data on the manage storage page? Ready to dump this app, I've already spent too much time trying to get this to work!!!
