Missing heart rate data

Got up this morning scrolling through the morning report, and everything is good. Closed it out and the report opened up again only for the watch to restart as I went to close it. Didn't think anything of it, but when I logged into the app there is a gap of missing data from 2:30 to 6:30 am. The data is in the watch just not showing up in the app. Has anyone else seen anything like this?
