I'm blind and I don't like Discord. They implement accessibility well, but they, Slack, Teams and the like have decided that I need to know the sender and time stamp of every message in the chat. Read to me for every message.

Jumping between screen sections is annoying because lists and headings are too nineties and the hell with them.

Captchas? Should I mention that for some reason they disliked one of my logins and put an inaccessible captcha? Maybe your unhappy blind users are still locked out and can't tell you for their issues. Good that I was registered with a gmail account and circumvented them by adding a dot in the email field.

Those are personal experiences and I don't know your previous solution, but for me Discord manages to be annoying in a very specific and unnecessary way.
