Kasa and ZooZ Zen34 switch all stopped working yesterday

I’ve been having the exact same issue as @newcliche where the manufacturer code was correct, but it still refused to change the driver in any of the interfaces. I went back and forth with Zooz many many times and they finally told me it was a Samsung issue after trying everything they could. I decided to give it one last try before giving up and paired it to my Zooz stick to check the firmware. Turns out mine was still on firmware 1.00. I updated to 1.40 and when I paired it to my Smartthings hub again, it now pulls the correct driver and works perfectly.

No way, I would’ve never thought of this! I’ll email zooz right now, thank you!!

Here’s the link to the instructions and the firmware files:
