Cannot connect to bot from Android

I can’t get the Android app to work. I’ve tried three different Android devices! Sorry, no Windows or Mac devices here to try with, I only have a Linux desktop.

The main problem is that the bot fails to connect after supplying the wifi password. It’s blue for a moment then goes back to red. The password is < 20 characters and doesn’t have anything unusual in it. Neither does the access point name. I can reach the status page at It shows version 3.0.0.

Also of note, on two of the devices the app just doesn’t fit right on the screen. There is a white bar on top, and the icons are clipped at the bottom.
