Just updated firmware of my Puck Pro from v2.66 to v3.20. While browsing through previous dive logs on the Puck Pro, the O2 display at the right side of bottom line switches to 30% after showing 21% for just a split second. All entries in the log exhibit the same behavior. Seems to me like a bug. Tried flashing the firmware again but the problem persists. Worse is I am unable to find previous versions of firmware to revert to.
