One of the most frustrating things as a seller is not having any form of contact between a seller and buyer.
I know that people can supply any description or info they’d like on their profile page, but this isn’t very well explained. In fact, I was unaware that I had a bio area until I snooped around the app.
Perhaps just a global bump or incentive to creating a bio/contact info would be useful, so that people are aware of its presence, which would hopefully help contact between members.
Also, a chat would be a useful alternative, and comments that can be expanded. (If comments are too long there is no way to read the whole thing).
