So I copied down the info, refreshed the page and the info is all still the same. Pretty sure I'm looking at the same wallet I used the first time. Still showing 0 txs though.
I imported the wallet into Electron Cash like you suggested. Worked great - I can see all the sats I put on scale.cash but don't think they've been used.
