HS-WD200+ Unresponsive in SmartThings

I’m having issues with the HS-WD200+ not responding to the ST app or to settings configured in ST. Everything worked for about a month but then I realized that I can’t turn the lights on using ST anymore. I used webCORE to program the notifications lights on it and they are working as expected and shows me the lights status when I use the physical switch so it’s clearly still connected to ST. When I power cycle the house/switch I notice that it will work with the ST app a few times then stops responding. It’s running the latest firmware 5.14. Has anyone experienced this before?
