Ratings and reviews

This is not a CodePen app, why is it asking to set up a profile instead of loading your existing CodePen profile? It's designed to look like a first party app but seems like a third party disconnected platform. * You are using the website's official logo and name on the product, how is that "clearly mention... it's not official"

this app is not best because my wifi is on and internet connection is also a good but app is not working properly

worst. I made all the code and everything. and when I want to save it or publish it just doesn't. I dont recommend this app to anyone
