Updated to Docker Desktop 4.15.0 (93002) for mac. Noticed that I had gotten logged out.
Tried to sign in again and sign in is failing now with a generic error message. Am able to login on the Docker website without any issues, so the problem is specific to Docker desktop.
Hey! Just got an email from support saying that my case was closed because my issue was solved. It technically was because I was able to login using the command line, but the default sign in flow was still broken. Might want to look into this.
