Descent Mk2 "Battery Saver" Bug.

I recently did an update on my Decent Mk2 to Software Version 16.30 (a266687).
I found that the Battery Saver switches off automatically after while.
I also found that Battery Saver switches off when I access my Activities list, not selecting any activity though.
This is a really annoying new "feature" that eats my watch's battery life unnecessarily.
With the old firmware feature Battery Saver would stay on unless I activated an Activity , then restored Battery Saver to "on" upon exiting Activity.
Is there a fix on the way or is there a way for me to load up a previous Firmware version?

Thanks in advance.
