Just to verify, is there any error message popped up on the app and had you adjusted the Gain value of MC setting? Please try to calibrate the IMU and stick and test again.

probaly been restricted again with the new firmware update, just revert back to an earlier firmware that will probaly sort it out ;)
The firmware will not restrict the speed of the drone. How do you think it is the firmware issue?
