I'm new to MM and don't understand what is going on.
I have about $10 ETH in a MM account at https://portfolio.metamask.io/
I had the MM Chrome/Brave extension installed but couldn't link it to the portfolio so I deleted it (it showed $0 balance and my ETH is still in the above portfolio) and reinstalled it.
Once again, I used the same Seed Phrase in the extension as in the above site portfolio.
So why doesn't my ETH appear in the extension?
