Subscription and unsubscribe issue

@josh I am having problems with the mobile app with subscription to events for tasker. I am encountering this error 400 trying to unsubscribe or resubscribe to a thing. I have added and removed it using SmartThings and I am still getting the error.

Can you clarify what you’ve added and removed using SmartThings?

Have you checked the SmartThings IDE live logs while you attempt to subscribe or unsubscribe? The error messages are generated there and usually provide some insight.
