If you were able to take camera measurements before but cannot anymore, it is likely because you have run out of free credits for camera measurements for this month. When this happens, you may see a notification in the app indicating that you have no more free measurements (see the below screens for reference).

If you want to unlock unlimited camera measurements, please consider subscribing. You can do this easily by clicking “Join” on the “Measure” screen or on the “Manage my membership” screen (accessible via the “Profile” screen).
