Thanks Ray, turning on “Special-Station Auto Refresh” option fixed the problem.
On a side note, “System 2” which was configured as “An Extender” before the upgrade. After the upgrade and resorting the config, the System wasn’t automatically re-enabled as an “Extender”. I also couldn’t find the option to turn this back on.??
The only way I managed to setup “System 2” as an extender again, was to change the Remote station settings configure on “System 1” which then prompted to change “System 2” to an “Extended”
Cheers
