@mrconorae So this is getting strange. I just got my account approved, and was able to log in, both on Firefox and Chrome on Windows.
Sorry for taking up your time, but would you mind sharing more details on which browser and OS you are using, and seeing if you are perhaps able to log in with a different browser?
I also wonder if there are any security/privacy settings that might interfere here, which has been the case for Misskey/Calckey.
