Hello - I went to trade OGN to ETH right inside of Trust Wallet. I was charged the ETH fee but the trade never executed and my OGN is still OGN with no increase in my ETH amount. There is a smart contract inside of the transaction history of my ETH, but no transaction history in my OGN wallet address.
When swapping tokens for the first time, you have to approve it first to be spendable. And, that is what you did just now.
Since you are done approving the token, you need to enter the amount that you want to exchange then press the swap button.
All in all, you will confirm two transactions: approve and swap
