    Hello, my Petrel 3 and my Perdix ai have the same problem after upgrade to v93. After my deco is finished at 5 meters the NDL doesnt return to 99 or other value. both computers shows 0 and DECO CLEAN, after 10/15 minutes of dive, only shows DECO CLEAR. If I download the dive to my phone, the profile shows correctly the 99 after deco.

    I love the new mini display functionality and the calibration history is a great new feature.
