To help me get started learning how to create contracts, I had 1 ETH sent from the Ropsten Ethereum Faucet to my MetaMask address. It arrived fine, but when I tried to send it to MyCrypto address it has never showed up -- after almost a whole day, although the Status line says Success. I notice that at the top it says, "[ This is a Ropsten Testnet transaction only ]" in red. Is it refusing to go through because of something to do with Ropsten? https://ropsten.etherscan.io/tx/0xe20eff34a5a8d60de3e61d2f9a914df9be507ea6a37d23dd86cd1f3ca37aa050
Previously I had sent ETH from my Uphold wallet to the same MyCrypto address, and that came through in short order.
You might ask why am I bouncing around between MyCrypto and MetaMask? Ha, I started by watching a YouTube video about Mist that had been produced 3 years ago, not knowing Mist has been shut down. It's too bad that people leave out-of-date content laying around to confuse people, which has easily happened to me! I was then referred to MyCrypto and then Remix (which recommended MetaMask as a wallet platform).
