Has anyone completed a transaction using Haveno?

Putting aside the difficulty with setting up the application (not impossible, installing is not friendly to non-tech users), I have not had too much luck completing a haveno transaction just yet. Last time I used Haveno there were not many Zelle/CashApp vendors. When attempting to transact with some vendors I got an error message along the lines of "arbitrator not available" which quite honestly I don't understand what it means or how to get around it.

I am hoping these issues are temporary since the network is literal weeks old. I am just wondering if anyone has had a more smooth experience using Haveno to aquire monero?
