I installed lametric with my iphone in my home wifi-network.
got the message that my iphone cant't connect due to I have to disable the guest account on my access point. but i have no guest account.
so I reseted la metric.
took my iphone via cellular and opend a personal hot spot. then I took my ipad to setup lametric via the hotspot.... but I got the same message!
I wrote a support ticket, but no answer so far...
could install an update somewhere else in another wifi.
after that I could connect at home in my own wifi.
now everything works just fine.
