This is the second time I have gotten a generic response via email. Once for a vBulletin plugin, which I don’t understand what couldn’t be the quality standard, and now for a progressive web app that uses Google Service Workers. Google has set the standard there, so if there is something I am missing these generic responses really do not help anyone.
Hello and welcome to Envato Forums,
Do you have a preview link us to take a look and see what’s the current quality of your item? 
Regards!
I included it in the submission. You must use a mobile device to see the Add to Homescreen and Push Notifications.
This is an addon to PlayTube, after speaking with them they said it was fine to sell my code to addon to their software
