2 days ago, I got my notice that it was time to update my Smartthings account to Samsung. Immediately after, all of my CoRE pistons stopped executing. I can see the evaluation change when the criteria is met, but the state itself won’t change unless I simulate. I’ve updated CoRE and tried repairing/ rebuilding all pistons.
If I create a new piston, it will work (for now) but I have a dozens that I would rather not reprogram.
So far, tech support has offered up resetting the Hub and uninstalling / reinstalling the classic app as their suggested fixes.
I’d appreciate any insights that can be offered.
