Apple Watch Series 7 doesnt't work correct

Hi everyone!

I have some troubles with my Apple Watch Series 7. Maybe somebody knows how to fix it.

1. Average time asleep is not tracked. I set a sleep schedule, but it doesn't show me any data except the average time in bed.
2. I have not been getting stand reminders. Stand reminders used to work a couple of days; without changing anything, it stopped. I have tried to reset the watch, turn off and turn on notifications, and pair and unpair the watch. It doesn't work.
3. Last but not least — when I open a workout goal watch constantly pauses a workout. It's so annoying.

I have the last version of software on iPhone and Watch, all notifications turned on. I don't know what else I can do.
