Permissions error trying to GetLoggedInUserFriends

I have been retrieving friends list in my Unity/Oculus apps for quite a while. I'm familiar with test users, application ID's, application data usage requests, etc. and have successfully retrieved friends lists this way for quite a long time. As of a week or so ago, GetLoggedInUserFriends has stopped working for my test app, and every new app that I create. The entitlement check works, the call to GetLoggedInUser returns with the correct information, but ALL calls to GetLoggedInUserFriends returns error:

{"message":"Permissions error","type":"OCApiException","code":200,"fbtrace_id":"A6dYwQaRL_JH1gbon3ByVtj"}

My logged in user is organization admin (shouldnt matter) and my app ID has ALL data use permissions granted. Can anyone think of something I'm missing?
