EDIT: It looks like SHM was having an outage yesterday Smart Home Monitoring Not Working
I like the way you think. On a more serious note, what you’re describing is a platform timeout caused by increased load or an internal issue and not related to the app.
I think it’s a timing coincidence. We release updates tend to coincide with ST deployments to their platform (Tues/Thurs).
We’ve been hearing/noticing timeouts on the platform since yesterday across many apps so I’m guessing it’s either a ST load issue or something in the deployment, either way it’ll sort itself out in a day or so.
To protect users from these issue we released a bunch of apps to check if the Routines executed properly or if the mode/SHM changes did their things and complete it for them if the platform didn’t complete/timed out for any reason.
