Hello.
Basically I have some devices from TP-Link (Kasa App) that work perfectly on the SmartThings phone app, when synced with Gear S3 it gets stuck on “Checking status”
Yup, and what @jmlt8 is experiencing is the same thing I get. I just stopped using my watch app until ST gets to fixing things. The watch app doesn’t sync well. For example, the phone app and IDE shows I have 267 devices, which is right, but the watch says 265. Automations and Scenes are out of wack too. Performance is also horrible, which I attribute to the number of devices I have (even though I tell it to only sync about 10). For the most part I just use Alexa since that’s everywhere in the house, and when I’m not here I always have my mobile. Quite frankly I haven’t used the watch app for a very long time, and struggle for a use case for me.
as @johnconstantelo said, it’s the 6 circles. I have also tested opening the app with device disconnected, it shows disconnected but when I turn on it just bugs on the phone app and turns “checking status” on the watch.
