Would it be possible to add to an option to allow the "@" rules (or whatever Apps and the Store itself need to work properly) without sacrificing the Secure Rules feature? I'm having problems with the Microsoft Store app -it won't open at all- and I think Secure Rules might be related. Don't know if Secure Profile can also interfere. While 5.1 is more 'hardened' than 5.0, it also seems a bit less flexible. If I understand correctly, the "@" rules are now completely disallowed with Secure Rules thus rendering the whole Apps environment problematic and buggy. Not a fan of Apps but I'd still like to be able to use them like before, while keeping Secure Rules enabled.
