Thank you for your submission. We have completed our review of “Web to App - Convert Website into Application with Android + OneSignal + Firebase” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.
Here is the comment from your Envato Quality team reviewer:
His item has a great idea behind it but I’m afraid this functionality’s niche has been sufficiently filled by a number of other great items here on CodeCanyon and elsewhere on the web and I think we’re reached a point of saturation. At this point, we’re only looking for unique variations of this feature: for another one to be approved it would have to have a couple of unique features that differentiate it from what ís already available.
