For the life of me, I cannot figure out what's so special about this app that it needs me to login from scratch every week and it cannot save my username and password. If all my social media and bank apps don't need me to login every 2-3 times I use them, why would the app that contrlols the lights in my home need that? Fix this, guys, please, you are embarrassing yourselves and once a customer like me has a couple of Sonoff switches, then they see this, they will just switch to another hardware supplier for the IoT needs.
