Hi
When you modify any WLAN settings momentarily clients get disrupted (in CLI you have to shut the WLAN first before modify any settings. In GUI when you do config changes on WLAN same thing happen in background)
That WLAN settings (FlexConnect Local Switching) applicable to "FlexConnect mode AP". So unless you change branch AP to that mode & properly configured vlan mapping there is no effect on that feature.
