PWA Builder Studio Analysis Site
I found what might be the best way to analyze and set up your UNA PWA app.
https : // checktest . dev / pwa-progressive-web-app
By entering the url of your UNA site, this will redirect you to the PWA Builder Studio where you can review your PWA checklist score, and work on getting your app to be ready to download as an Android Google Store app and an iPhone app.
You will also need to use your UNA Designer app in UNA Studio to start this process.
If you go directly to the PWA Builder Studio site, you will be instructed to start a PWA from scratch, which is hard to follow. However, it you use the checktest dot dev / pwa-progressive-web-app website page, it will redirect you to the PWA Builder Studio's PWA analysis and development section, where you can work on the PWA very easily. And follow its suggestions.

You may also, download a version of your service worker and manifest files from there with additional tweaks added to replace the UNA files.
When it all checks out, you can then download the apps you need for the phone stores or upload them into your UNA site for download from there.
Using the direct link to the PWA Builder Studio for you UNA site, seen below
https: // www . pwabuilder . com / reportcard?site=https: // www . mysite . com
You can add an html block to your UNA Studio Dashboard for relative links and add this link to your PWA builder page. In this way, you can update your PWA if needed, as well as check on its score.
