My Fenix 5 is great, and usually when I t ravel it automatically adjusts to the new TZ.
However on this current trip to PST, it keeps reverting to my home CST.
If I manually go to settings/time/sync to GPS, it will sometimes then update to PST (where I am now), other times it is wrongly falling back to CST, and says it is already sync'ed.
Then for a few ours/day it will be OK again.
I did power off/on, no fix.
The only thing from their support was a factory reset - but I am reluctant to do that, as I would have to redo all settings and install all apps again - Ugh...
