Hello Vinz,
the updates went fine like you described, thanks for that.
Still 1 issues though!
* the host name has changed to something like WT2CEA7F3503A0
The other issue has been solved by setting the group token in the policies as well
(the device jumped back to the device group where it was a member before the upgrades)
You can do that in ThinOS 9.x – Services – WMS Settings
