The studio page signs me in but doesn’t show the usual studio or any of my stuff. It just has a button with my Eth address and that clicked just lets me disconnect.
We’ll need a bit more information to figure why you can’t see anything in studio.
What browser are you using? Have you signed Metamask to login? A few notes that will help us look into this further:
MacBook Air / Chrome / MetaMask Signed in as usual. Just no studio.
UPDATE: I tried in an incognito window and was able to get the studio when I signed in. So I am guessing that the browser had cached some old code that no longer worked.
