Smart plug not working with schedule

One of my smart plugs is no longer working with the schedule set in the app. I would assume it is an app problem since the schedule is set in the app but my other smart plug is working just fine. So maybe the plug has gone bad. It stopped following the schedule about a week ago. I have had the app forget the device and reinstalled it. Didn’t fix the problem. I had it reset the wifi connection, also no use. Any suggestions? It doesn’t seem like anyone checks the whatsapp beta anymore.
