Your captive portal is one of the best things you have, I'm not sure why you dont advertise it more, people love it and use it very, very frequently.
It is very important for a lot of businesses. I've noticed that it lacks Instagram authentication, your developers are great, I know you'll be able to add Instagram as it is the biggest social media in te world.
Very unfortunate that you are not able to asks your users about a survey every once in a while to get to what is really imporantant to them. I'm sure that Captive Portal is in the top10.
I mean you already beat Ubiquiti with your quality and stability, hopefully, we will see this feature come soon as well as user research and surveys.
