Just a clarification on #2. Is this condition now fixed or are you noting a current issue?
Sorry for the confusion, both of these items were fixed today.
Is it possible for an end-user to determine if this update has been successfully installed?
Currently no. If you want to be super safe, a power cycle will always get latest firmware…but you should not have to do that. Firmware is pulled down by the device as soon as it is deployed.
