UPDATE

Summary: It's not possible to use the "join district" button.

Description: If you try to follow a friend or group member using the "Join District" Button it's not working.

Steps to Reproduce:
1. Be in group with someone.
2. Open the Group & Friends Menu.
3. Select a Group Member or Friend.
4. Press "Join District".

Results: You get the following message.


Reason: The reason that this appear is because the person you trying to join has not enabled "Share location with searching player".


Expected Results: I have different expected results.
1. If the person isn't sharing his location there should be a message for that. (Not needed cuz you can see group member and friends district anyways)
2. If you trying to join a group member or a friend you should be able to join him even if he is not sharing is location. (Because you can see his district anyways)
