I've been using it via wifi for over a year. Lately maytronics has asked me to reverify several times. No biggie. But today it said it couldn't connect to the robot. So I figured I'd just switch to Bluetooth mode temporarily. It gave this warning that I would only be able to use Bluetooth but didn't give me an option to back out after that. Now it is stuck in Bluetooth mode and I can't get it back to wifi mode. Nor can I find any instructions to do so. Anyone have any advice?
