Seems the index.html doesn't work at my end. By press Receive or Sent will lead me back to the https://qrss.netlify.app/ page which doesn't work offline.

I tried Brave for PC, installed the page, copied the installed webpage to my offline pc and it worked!
thanks for the info :)

For Docs. I think it's great, but i'll probably need to add an additional tutorial on how to use the PWA.

For index.html file. I think it's going to have issues with not being up to date if it's not built as a CI and is integrated directly into the project.
