Recorded Sleep Deletes After Manually Ending Sleep on v23.00 Software

Same... Tactix Delta, v 23.00

Same here, it was back to normal after two days of doing this and hasn't happened since. 

I have the same problem on my Fenix 6 Pro. I don't really want to reset my watch to factory settings and loose all my activities on the watch without knowing if it works. Powering on and off does not solve the issue. Hard Reset seems to be not working for me as I have Assistance Alert set to the top left button. Any workaround for this? 

Keep the button pressed beyond the Assistance alert until it powers off

Thanks for the reply.

Did the "Reset Default Settings" via the Menu. This seems to have resolved the issue!

Hope this gets a fix, so it doesn't happen again. 

Same Problem here. Reboot and soft reset (hard restart, however you want to call it), which I periodically and definitely always after a firmware update do, didn’t help. Really don’t feel like resetting the whole watch…!

Also, sleep recording is wonky when doing late and night shifts since the update. Always cuts the first hours of sleep. Didn’t happen on this extend before.

Until now I did not dare to update to 23.00, because I am on a long trip full with sport activities. 

Let’s see it from the opposite side: is anyone around who has not experienced this phenomenon after the update?

I regularly end sleeping manually, so for me updating to 23.00 depends on whether it is a general bug, or just the question of some unlucky combination of several things/settings.

Your update to 23.00 will likely cause u to lose the first night of sleep and HRV data, after the first night you should be back on track. It's pretty nice not having to end the HRV logging when you wake up also as its now automatic and ends when sleep ends.

I've actualy never lost sleep and HRV data during the night when my watch updated. And I think his question was related to the bug reported in this thread (which honestly cannot be answered, since not everyone seems to have this bug)
