Webcore isssue in the new smartthings app

Hello folks, I am unable to add new devices to webcore smart app. I am getting this error in the new smartthings app. Is anyone else facing this issue? I was able to add new devices to webcore using the classic app. Thanks in advance.

Try rebooting your hub in IDE

Make sure to have all DTH in the list, or at least the one you tried to use.

I am getting that message a lot as well, mostly from the new app, the old app seems to be less brittle.

I received the same message but I just clicked through it and everything worked fine?
