@Emil via Alexa routine, and yes I've tried removing/recreating on Alexa itself. Triggering routine directly on Alexa works fine. As noted, the setup has been working for 2+ years, until it didn't.

I've had this button working with the same trigger for 2 years, when it just suddenly stopped actually triggering the associated actions. The presses register/show in the Flic app (button push animation) but nothing happens. I configured a new button the same way, even tried with alternate provider for same routine, no dice. The smart plug responds as intended when triggered by other methods (its app, Smart things, Alexa, etc) but not via the Flic button. All other Flic buttons on the same Flic hub still work with their respective devices/triggers, just not the smart plug. Again, that setup has been working fine prior to today, and any new buttons tried with the same setup also don't work. I've even reset the smart plug to no avail, so I'm out of ideas. Any leads?
