What's Wrong?

The Create button remains grayed out and unclickable when setting up a new Routine in Claude Cowork, even after all required fields are fully filled in. The button never becomes active regardless of what changes are made to the form.

What Should Happen?

Create button becomes active and clickable once all required fields (name, instructions, trigger, connectors) are filled in.
