That's pretty much it. I've got my dedicated Sofabaton SSID that only has 2.4ghz and only one AP to keep from confusing the software. This worked once upon a time, but no longer. I've been trying it on and off for the past few weeks -- no new app updates in that time though.
Trying to reprovision the hub with my wifi network (solid blue until I hold the button and get flashing blue light)...
The instant I touch the "blue light flashing, next" button in the latest iOS app on the latest iOS on a new iPhone 13, it crashes.
