Hi
I was getting my website published as an app on Google Play
So, as I don’t understand anything about programming, I found out about PWAs and I used this site to generate one, the pwabuilder, but when it comes to generating the application, it crashes with this error
“start\_url is required and must be a string with a length \> 0, must be a valid URL, and must be relative to the app scope (if specified)”
What does that mean?
