This is on the hosted interface, right? I can sorta understand that, especially when the ads are for their own gear. But if I start seeing ads in my locally installed copy of Unifi, this will be a problem.
Well that is disheartening. I've been pretty happy with my choice of Ubiquiti gear for home, it was a vast improvement over the consumer-grade gear I had been using before, but if I'm going to start seeing ads on my own server, I'll be looking elsewhere when it's time to upgrade.
