I bought my 2nd RT-AX86U (not pro) for my vacation home overseas. I wanted to set up a VPN connection back to the U.S.. with ExpressVPN but I see the VPN Client tab is no longer available in latest version of firmware (24231). On my 1st router of same name I am running Merlin and really like VPN director as it allows me to control things at device level. My apologies if this has been asked before but what's going on with the missing VPN Client tab? Is there any way to flash a prior firmware version to get this feature? Thanks......
