New Firmware 1.01 for DDJ SX causing issues

Hi I updated the firmware of my new DDJ SX to version 1.01.

Now I have the following issue. The Jog dial has become very accurate (and thus slow).  

With Vinyl set to "off", scrolling through songs becomes very slow (i.e. have to turn the jog lots of times).

The update was meant to "Optimize the touch sensor sensitivity adjustment range for the jog dial". This might have been done, but for sure confuses me with the issue explained above.

Question:

• Can I adjust the sensitivity of the jog dial?
• If not can I revert back to firmware 1.0
