I am having a similar problem here – I used to be able to trigger Smartthings Routines via the SharpTools Tasker plugin but this no longer functions correctly. I will mention that I had (of course) to go back to the Smartthings Classic app for Android, once I realized the new app (which I didn’t like anyhow!) no longer implements Routines. I have tried recreating the Smartthings Routines and following all the recommendations made in the post to which this is a reply – but no change. I also tried completely removing and reinstalling the Smartthings Classic app – did not help. What am I missing here?
