Especially given that I am running this on localhost, which is never "offline", how can I test that all the stuff I did in step 6 actually had an effect?
Maybe I should be testing from my phone using some kind of localhost-to-internet tunnel?
Thanks for the feedback. I've rewritten the codelab from scratch and believe I have fixed this issue. The code has been updated, and the new guide is now live.
If you find any issues with the new codelab, please let us know!
