Sense showing wrong sleep times

[KittyBee]

My sleep times recorded last night are incorrect.  My Sense says I was asleep from 8.20pm, when in fact I didn't go to bed until 10.00pm.  I was reading for quite a while before I went to bed, but I wasn't absolutely still during that time, I did move.  My waking up time was correct, at just after 6.00am this morning.  Also, I only got a 'simplified sleep detail' for last night, even though my Sense was in the correct place on my non-dominant wrist.  There is no Stress Management Score either (responsiveness, exertion balance, sleep patterns), although this feature has been working up until now.  I'm not a very 'techy' person so am nervous of rebooting software, deleting and reinstalling app etc as dont want to delete my previous data.   Any ideas anyone?

I would say that if this was a one-time issue and the only time this has happened it could be just a minor temporary glitch, and leave it alone. That's what I would do. If it continues to happen then I would dive into detailed troubleshooting.
