Since Monday I have no more sleeping registration. I post a picture. The only thing I've made on Monday is the installation of maps. No fw upgraded!
I'm still in the Beta 2,64...
- My 945 is set as prefered as instrument in GC
- My settings in Fisio on the watch are all ON
- My pulse OX is set only for night, but it was the same before Monday
Somebody has any idea?
jumpstart the watch 
press and hold the light button until the screen goes dark
turn it back on, sync the time
? result
also have a look in the sleep folder on your watch
are the fit files missing from monday until now ?
happy & safe sporting
thank you,
strange that Garmin only keeps 1 file
others chime in for help, please
there is data from today in that fit file
go to Garmin Connect Web and import that file into your account
? does it say the data is already there
check on every platform your activity tracking settings
check Garmin Connect Web, Garmin Connect Mobile and your watch settings...again 
also is there sleep data on Garmin Connect Web for this week ?
happy & safe sporting
Today I insered manually my time sleeping. 945 registered nothing….
upload the fit file from the sleep folder ?
three things you can try
1) redo all activity tracking settings on all platforms
2) reset to default the Garmin solution
3) wait until someone chimes in with more knowledge
happy & safe sporting
success 
Now tried deassociate from GC, reset 15 sec, sync Gps, restart GC and reassociate 945 to GC...
Go to sleep now, I hope very well 
....and tomorrow after a run and a coffe will see if data will magically appear! 
Eureka! Well done, now it works again! Thanks very much for support
