I think Upwork could find some contractors on Upwork to polish some rough edges. Like this login screen.
Username or Email, Continue with Email is like asking you want fries or salad, continue with salad. And I wasted time trying to remember my username.
Then I was invited to join a call.
But the invitation was sent to one of my other email addresses, so I got a message to go back and click on a non-existent button.
After receiving the invitation on my upwork email, I got a message that I needed to switch to that company. That's fine, and even the cryptic room name is fine, but Wrong Context in big bold letters screams you made a terrible mistake, turn around!
