Wyzeplug turns on by itself

I have one Wyzeplug connected to a stereo amplifier that plays the surround portion of my TV. When there is no surround, it stays off - supposedly, When there is surround I have Alexa turn it on, and then turn it off when the surround is gone. We had an Internet outage last week, and since then the plug turns on by itself. Is there anything I can do to get it back to only turning on when asked? I’ve tried unplugging it for a couple of minutes, but that made no difference.
