Joe, Not much noise yet so I’m replying-all.
First, thank you for pursuing this effort. I lack a “real” machine and so welcome alternate J delivery vehicles, particularly when they don’t involve paying Google for VM time. iPad Pro running 15.4.1: On both Chrome and Safari, expressions return no results and Labs do not seem to launch, though the examples do load into the editor. iPhone 11 running 15.3.1: Ditto. Perhaps I’m doing something wrong. Happy to take guidance or perform specific diagnostics. Thanks again.
