Applewatch sleep monitoring has no data.

There is no data for Apple Watch sleep monitoring. Solutions:

1. Restart the watch.

2. Unbind the watch and rebind the phone again.

3. Turn on the watch "sleep" focus mode manually when you sleep at night.

our operation is to rebind the mobile phone once (aw will not be displayed in the sleeping data source immediately on the day of binding, but it will be displayed the next day after sleeping for one night), and the data will be available the next day. Some friends also said that it is enough to manually turn on the "sleep" focus mode at night. Those who don't have data can try these solutions one by one. If they can't, contact Apple technical support for help.
