Sleep tracking on a new Fenix 6 Pro Solar not working

I don't know what else to do. Could it be that my device is faulty? If I don't get it to work, I'll have to return it next Monday and I would very much like to avoid that

And what about pulse and stress tracking? Do they work? Can You attach pulse graphs?

Thanks for your response. Pulse, stress and breathing seem to work normally during the day but stop recording data during the night for some reason. They all look like this. 

This morning I reset the watch to the default settings and I'm not touching anything until tomorrow morning. I hope it will do the trick. It's a bit frustrating just being able to see if it works once a day. Fingers crossed

This graph looks rather strange.

1. Did You set up Battery saver for night hours? It looks like that pulse measuring stops working at night, maybe You haven't switched it on while the watch is in Battery saver mode.

2. Stress and pulse graphs look like You often take off the watch during the day, is it true?

1. I didn't and I have check that same thing like a million times to the point of thinking that I'm going crazy.

2. I took it off a couple of times today to reset the settings. I wouldn't say it was often, but yes.

Thanks again for your response 

I has been like this since I got the watch and I have never changed it.

Now that you say it, it does look like I got my watch off many many times today although I only took it off a couple times early in the morning. That's weird. Thanks for pointing it up

Yes, It could be a good idea to make the reset. Let's see, what's gonna happen. But really strange, beacause sleeping time is showed on both graphs, but there is no pulse and stress during that time.

Does sleeping time shown on the graph corresponds to Your real sleeping time?
