I just had this issue occur as well. One started cycling on and off rapidly on 6/20. Luckily I caught it because the device it was powering makes a beep when turned on so I heard the constant beeping. Then today I just had another one start the same issue. My biggest concern is damage to the device plugged into it having it power on and off constantly until I notice the issue. I have almost 20 smart plugs in use and I feel like I need to remove them all to be safe.
