Nothing here, and I use Fitbit all the time. I'm on Wear OS 5.0, Android 14, September security patch.
Yes sir! And I wear it at night for sleep tracking. I'm also on the latest WearOS.
Thanks for your input. Because I bought the watch just at the point that Google paused the Wear OS 5 update, I am still on OS 4, Android 13 July (really August) security patch. I guess that I can hope that the update, when re-released, will fix the restart issue. I know that I could flash the update, but I keep thinking every day that Goggle will re-release the official update "tomorrow."
I know that I could also strap on my original Goggle Watch (which works perfectly, by the way) if the restarts were irritating enough. However, so far, I more perplexed than irritated and know that Google will definitely re-release the official update "tomorrow."
I also wear the watch at night and, strangely, that is one of the times that I encounter the odd restart. I tried all of the fixes shown on the Google Pixel Watch Help Community and Reddit, but, alas, no love.
