I'm sorry, I fail to see where they said it
WAS a platform issue.
They simply stated they were not responsible for platform issues, which is a general response they give when someone blames a platform for their failure. Did you want to post the chats with Finamark where they said to be cautious on mobile? Or the ones where they said there was nothing they could do because it appears you're the one who placed the trades? You even said, "Ah ok, I need a PC." I have them if you need me to post them. They also linked you to the help manual where it states

You blaming Earn2Trade for a what you feel is a trading platform issue is like blaming a broker for a trading platform issue. Almost all brokers list out the trading platforms that can connect to them but state, as we do, they are not responsible for any potential platform issues. If this had happened on the real market, the broker is not going to just say sorry and give you the money back... the money was lost due to no fault of their own.
