New app - Webcore - Samsung TV

So I use the classic app for pretty much everything. I have a 65KS900 tv that worked great before the integration was broken. The TV can now be used again with the new app.

Webcore doesn’t see the TV to add to usable devices in the new app, and the tv only shows up in the new app. Not the old. Am I missing a step here? Or is it not usable with Webcore anymore?

Not missing any steps. The TV doesn’t use the old groovy based backend that webcore does, so they aren’t compatible. You can try the custom automation creator in the new app. It’s basically a webcore lite.
