I'm trying to link GA's User ID feature to my iOS app, but this doesn't seem to be working. From the documentation, I enables a User ID capable view (profile). Then, I set the userId field.
My code: AppDelegate.m
id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];  // You only need to set User ID on a tracker once. By setting it on the tracker, the ID will be // sent with all subsequent hits. [tracker set:@"&uid"        value:@"userIDTest"];   // This hit will be sent with the User ID value and be visible in User-ID-enabled views (profiles). [tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"User Test"            // Event category (required)                                                       action:@"User Sign In"  // Event action (required)                                                        label:nil              // Event label                                                        value:nil] build]];    // Event value  However, in the analytics dashboard:
  I can't seem to find one place where I can see the user id.
