I recently purchased the Samsung Watch 3 I believe. For some strange reason when I add my period on my phone to track the watch shows 1 day behind. Example. I say I started my period on Monday on the phone app for Samsung Health and on my watch the widget shows it started Sunday. I mean I can live with lying to my phone since I like the correct date on my watch. I just wonder if others have been able to fix this on their watch or if the program just needs a correction and that will take a long time to even notice since its been out a while and hasn't been corrected.
