vivoactive 6 - constantly rebooting and sync problems

I have been having constant problems with my vivoactive 6 since receiving the watch a week ago, so far it has been a big disappointment.

The watch reboots at least 20 times a day if not more often, I think it mostly happens when the watch is trying to sync although I am not sure this is the case every time. Other things I notice is that steps are often lost during the day, and that the watch keeps reverting to energy saving settings I changed earlyer. Both point at syncing problems.


Things I have tried:

* the app on my Android 14 smartphone has no energy restrictions

* the watch has been marked as a safe device on my Android phone (as suggested by customer service)

* I have disabled all energy saving settings on the watch (although this is hard, since the watch keeps trying to reset this setting)

* I have applied a factory reset several times, and removed /reinstalled the connect app on my phone.


Thing that strikes me is that the watch is also often rebooting even when I switch off Bluetooth on my phone (so that sync wouldn't be the issue)

Is anyone using this watch with correct step counting, no syncing problems and no constant reboots?
