If your step count for the day has reached 30,000 steps, an error message may appear saying "Maximum number of daily steps reached."
This problem is caused by a communication error that creates a discrepancy between the "actual number earned" and the "number earned on screen."
If this error appears, please check your earning history screen to see how many step-count gems you have already earned, since you have probably already earned step-count gems 10 times.
We are working on modifying the app to prevent this problem from occurring.
