Unity Remote 5 not working on my Nexus 6 - Marshmallow.

I can't get Unity Remote 5 to work on my Nexus 6 - Marshmallow.

The problem seems to be that Marshmallow needs you to set mock-locations per app and Unity is not listed. So, when I choose "Select Mock Location" it doesn't appear there.

I'm guessing that the permission for mock location is missing in the Unity Manifest. Am I correct?

If so, what can I do? If not, what am I doing wrong?

p.s. I have set the correct settings in the Editor.

Something else that is weird is that when I rotate my device Unity Remote rotates even though I have it fixed in portrait!
