Hi there! I understand that your Friends app game isn’t advancing to build the next city. To help you better, could you tell me if the game is stuck at a specific point or if any error messages pop up when you try to progress? Also, is this connected to a Facebook account or are you playing solo?

Meanwhile, here are some initial steps that often help resolve issues like this on your iPhone:

1. Restart the Game: Close the app fully (swipe it away from the app switcher), then open it again.
2. Check Internet Connection: Make sure your iPhone has a stable internet connection (Wi-Fi or cellular data).
3. Log Out and Log Back In: If the game is linked to Facebook, try unlinking your Facebook account from the game, then close the game, reopen it, and link your Facebook account again. This step has helped with similar issues reported by players1.
4. Update the App: Check the App Store for any updates to the Friends app and install them.
5. Reinstall the App: If none of the above works, you might want to back up your progress (if possible), uninstall the game, and reinstall it to clear any corrupted files.

Could you try these and let me know if the problem persists? I’ll be happy to guide you further!
