title: Adding Liquidity to Ropsten RPC Error: execution reverted: TransferHelper: TRANSFER_FROM_FAILED
body: <p>I deployed a smart contract on Ropsten, all functions seem to work fine, however I cant seem to add Liquidity, I am doing it via the UI on <a href="https://app.uniswap.org/#/add/ETH/" rel="nofollow noreferrer">https://app.uniswap.org/#/add/ETH/</a></p>
  <p>Im getting in my console log, RPC Error: execution reverted: TransferHelper: TRANSFER_FROM_FAILED</p>
  <p>I have manually approved my tokens, yet I still receive the error, what might the issue be?</p>
