This will explain the watch settings fischest but not the watch face settings. This is a recurring problem with the fenix 5X which I recently read may be related to synchronising with wifi/PC/mobile. I read in another thread that if you stick to one synchronisation method, the watch face settings do not get lost. This fits what I have seen since I had not seen the problem for a very long time, but hit it again shortly after synchronising with both wifi and the PC. Have no seen it again since going back to exclusively syncing with my mobile via bluetooth. But I do wish it could be fixed.
I'm fairly new to the Garmin world as I've only had the 5x for a month or so. I think I've seen this mentioned but I can't seem to find any posts right now. I have settings reset to what I assume are defaults for no apparent reasons. For instance, my watch face (Gearmin) settings randomly go back to default. I also try to turn on my sound notifications but at some point every day they go back to "During Activity" or whatever. Same issues with the order of activities at times. It's just really annoying. Is this a known issue and anyone have any suggestions on a remedy?
