Hi @green-telephone-55648, the user id is hardcoded, but can be overridden by a query parameter. Try opening these urls in two tabs: http://localhost:3000/minimal?user=tab1 http://localhost:3000/minimal?user=tab2 This is not obvious and maybe we should assign random user IDs to make this work out of the box.

I have already create a random user id 🙂
