Not clear at all. I looked up the company, opened the website, and there are some "get the app" buttons, but the website does not indicate that the product is an app-first experience at all.
The submitted article even mentions it as a "shopping site", not an app. And looking at play store reviews, it doesn't look like the app is any better. It's filled with various technical issues and 1 or 2 star reviews.
So excuse me for having this crazy assumption that if something is being sold for over a billion dollars, it should at least somewhat work.
If I were Etsy, I would probably buy it for the community and marketing talent, fire every single dev and start from scratch.
Their app can't even properly show me clothes based on my preferences: https://twitter.com/dmitriid/status/1400084936372199429
It only goes to show how horrendously bad the original market was.
The disdain some people have for what is not their niche is crazy. Not everything needs to be a SAAS. It's pretty clear this is meant to be used as an app and it looks like you did your best to ignore it.
