I'm not sure if this actually a bug-- it may just be an issue that only I am having.
I was attempting to ensure that my email was up-to-date before applying for the beta, and I received a prompt that said I would receive confirmation; however, I did not. (Yes, I did check my spam folder.)
I then tried to use both the password retrieval link and the beta application link, with the same result.
I've asked in the Discord server, and it seems others have received their corresponding emails just fine.
