Logitech Harmony Hub/Smartthings Integration

I am recently started using my harmony remote and hub and integrated it with Smartthings. I followed the directions on the Logitech website through the Harmony app. It works when I initially set it up to assign a button to turn on a Z-Wave light switch. It works for a day or two then when I press the button, it doesn’t turn on my switch. It works after a go into the mobile app. I did some troubleshooting and found that the connection to Smartthings it reconnects after going into the app. I was wondering if anyone has experienced this issue or has solved this issue. Is there a workaround? I was looking at IFTTT but i could see a way use the buttons on the remote to trigger a Smartthings switch. Just wondering what else I can do.
