Also trying to sign up for a paid account and hitting a bunch of issues.
Just messaged you on Twitter (because Contact Us seems to be broken) but would appreciate help wherever if possible!
1. Have entered credit card details but still can't create an additional workspace?
2. Unable to transfer a workspace (is that an "Organization" feature? the web app just hangs, and the REST API said "Workspace owner must be an admin of destination Account", which I don't understand).
3. Tried to use your "Contact Us" button but it just hangs at the "Just checking: are you a robot?" and never gets anywhere.
