yes I could add the app with my test accounts but some users are still reporting a greyed out install button and about a week ago we literally stopped dead gaining new users and have started decreasing users now which is very weird since we had good momentum but then we just stopped dead. So something is definitely wrong.
Also this call is very flakey v = data.get("viewer").getData(); and often returns NULL in the wrong case
I have to say your platform has been very frustrating to develop on .... help is appreciated here
