Varia Vue Headlight Camera. Charge light no longer goes solid

Since the latest update the Varia Vue Headlight Camera charge light does not go solid green when fully charged.

I installed the update last night  and noticed at the time that the light stayed flashing.

The device does power on normally and does appear to have been charged.  But U left it plugged in overnight and the Charge light was still flashing in the morning.  It was fine before applying the latest update.
