I have the game running correctly on various iPhones and none showing the issue you are experiencing.
I have strong suspicion some data corruption has occured during the recent update on your device and to clear this problem, I guess you might need to perform a re-installation of the App. But before you do this, please ensure you have some backup or ways of recovering your progress first. The plan of action I recommend as below.
1. Screenshot or note down your player ID (Just in case something goes wrong and you need assistance from the Help Center)
2. Register your email address with the App so this provides you an alternative way to recover your progress,
3. Use iTune to backup your iPhone.
4. Once all of the above 3 steps are done, delete the game and perform a re-installation in the hope the fault is fixed.
The problem was just solved without me doing anything. I guess that there was a problem on the server side and they solved it.
