This started happening to me today prior to updating to 3.77.  Updating to 3.77 didn’t change anything.  I have a Charge 3.

@NanaPamJ  @Jktn   I still had v 3.76 yesterday and this happened to me, too.  I thought this was from the switch to DST.  This clock change can affect data on the Fitbit app.  My heart rate trace from Sat - Sun has a two hour gap, not a one hour gap.

I'm hoping this is all fixed today.

UPDATE: I got the 3.77 update after my initial post.  Then I did my morning workout and everything looks normal in my exercise details.  The exercise details from 3/12 aren't fixed and I don't think they will get fixed.  The time change corrupted the data.  I am a Fitbit user since 2013 and this happens every time switch.

Yes everything worked fine the next day for me.  Must have been the DST switch like you suggested.
