Hello,
I use a Tactix 8 Solar with Beta version 15.32.
I bought the watch 1 month ago. Since the first SW Version, which was installed (I Think it was 12.53) I detect the same error / bug in Power Mode.
When you go to:
Watch settings -> Activities -> Run (or another Activity) -> Run Settings -> Power Mode
it shows always "NORMAL"
Also when I change the Default Mode from "NORMAL" to maybe "EXTENDED" it shows every time "NORMAL".
I think it is a bug.
