I'd love to hear it! It is a problem that is slowing getting taken care of across the board (because it is a requirement of Visa/Master Card to have guests separate), but it is a problem I commonly see in various ways. Every piece of technology will have problems :) That's just part of the game. We find them and fix them. Ubiquiti had some problems recently announced. https://www.zdnet.com/article/over-485000-ubiquiti-devices-vulnerable-to-new-attack/

Yeah, Ubiquiti just kind of popped up out of nowhere and started making a big impact on the market it seemed. I really only hear good things about them.
