As noted in the other posts, i'm adding my own post here (community guidelines ask we start our own post)
When I attempt to login to the developer sandbox, after I enter my 2FA code, I'm sent right back to the login (as the sandbox headers show briefly). I've sent an email for support to developer-relations@devrel.clover.com but no answer or acknowledgment yet.
I have also tried clearing cache and different browsers.
